Chapter 650 The meter wave radar is getting stronger and stronger

  Wasteland Village Base.

“Hey, what’s going on today? The J-31A is back again? And it’s also black-skinned?” Pilot Zhang Yongchao looked at the plane that appeared in the parking area and asked very curiously.

The first batch of carrier-based aircraft pilots have graduated and have all flown on the 001 aircraft carrier. Zhang Yongchao belongs to the second batch of pilot students. Like the first batch, they are also studying hard and practicing hard to get on warships as soon as possible and become qualified carrier-based aircraft pilots. .

Their usual training is either a trainer aircraft or a single-seat J-15. Although the J-31A was stationed here some time ago, after this aircraft completed the takeoff and landing of the aircraft carrier, it left the wasteland village. There is no need to stay at the base anymore.

Now, I unexpectedly saw another J-31A, and it has also been coated with stealth coating. What does the sudden appearance of this aircraft mean?

There were some ground crews busy nearby. Zhang Yongchao walked over curiously and asked one of them: "Hey, brother, what are you doing here?"

 “Maintain the aircraft.”

 “What happens after maintenance?”

 “Let go.”

 “What happens after the flight?”

 “Go on and take care of it.”

Zhang Yongchao shook his head helplessly. This is a chicken-and-egg answer, a never-ending cycle.

"Forget it, we have confidentiality rules. If you shouldn't pry, don't pry. Hey, it seems that a Yunba is flying over?"

Yunba landed on the runway, and the cabin door at the back opened. Then, large boxes were unloaded one after another, and a row of large characters were spray-painted on the outside: Capital University of Aeronautics and Astronautics.

“What is this? A drone developed by a university in the capital?”

"That's right, it's a drone. This is our latest Seagull drone." A person who got off the plane said and began to instruct everyone to unpack. After unpacking, Zhang Yongchao opened his eyes wide and looked at it in disbelief. The drone inside: "Is this a coaxial inversion structure?"

The Navy has imported Lao Maozi's carrier-based helicopters, which have a coaxial reversing structure, are short and tall, and are in sharp contrast to other helicopters.

The same is true for the aircraft in front of me. It is unpiloted, so it has no cockpit. The entire body is like a short and thick airship. There are two rotors on it, and there are only two rudder surfaces at the tail. Tail rotor, this method makes the rear mechanical structure simple, while the aerodynamic force is symmetrical, the controllability is good, and it is very suitable for unmanned driving.

This is the first drone flown by the Capital University of Aeronautics and Astronautics in 1995. It has been improved and improved in the following years. Now, it has finally been put into use, and ten of them have been brought! The R&D team is very excited.

"This is too strange. Is this a big move?" Zhang Yongchao said curiously.

“To test the air defense system of our new warship, our seagulls can fly low against the sea to see if the air defense system of the new warship can detect us.” said the visitor.

 New warships, air defense systems? Zhang Yongchao immediately realized: "It's our 052C that's about to be tested!"

“Report, the base leader ordered that all pilots go to the conference room to gather for a meeting!” At this moment, an orderly ran over and shouted to Zhang Yongchao.

 “Got it, I’ll be there right away!”

 The meeting room at the base was bustling with excitement. When Zhang Yongchao entered, he heard them all talking in low voices about something like 346 radar, hundreds of targets, etc., which kept reaching Zhang Yongchao's ears.

"Okay, stop talking, let's have a meeting now!" The base leader walked in and looked at the lively pilots below: "We have just received a mission. In order to test the air defense systems of our 052B and 052C destroyers, we need to dispatch ten aircraft , as high-altitude targets approach the warship, we plan to dispatch five J-15s and five training aircraft, flying at an altitude of 20,000 meters and 15,000 meters respectively."

“Report, is the J-31A also going to be mixed into our formation?” Zhang Yongchao raised his hand.

"It's not your turn to speak yet!" The leader glanced at Zhang Chao dissatisfied. No matter which batch he was in, there would be highly skilled pilots. Not only were they highly skilled in flying, but they also had a bad temper, just like this one. Zhang Chao was a bit undisciplined and would interrupt when the leader was speaking!

"The J-31A will fly at an altitude of 18,000 meters, sandwiched between our two formations. This arrangement is to better confuse the other side. At the same time, our five fighter jets each carry two YJ-81 anti-ship missile target."

What?

At this moment, the pilots couldn't help but cheer.

Missiles are very expensive, so they usually have no chance to shoot missiles. Occasionally, they hang rocket launchers under the wings and practice shooting at ground targets. This thing is dangerous and has no sense of achievement.

Now, they finally have a chance to shoot missiles!

 Missiles are big things! Moreover, it is an anti-ship missile!

“Report, I have a problem!” Zhang Yongchao raised his hand again.

"what is the problem?"

"I think the range of the YJ-81 missile is too close. We need to fly fifty kilometers away from the target before launching it, and our route is also limited to high altitude. This is very inappropriate. I suggest that we fly in at ultra-low altitude. , Only in this way can we better simulate actual combat!"

"Ultra-low altitude? According to the exercise arrangement, targets at ultra-low altitude and within fifty kilometers belong to the shooting zone. The target warships can launch missile attacks without hesitation! Zhang Yongchao, do you dare to fly over? You are not afraid of being shot down by Red Flag Nine. ?”

“I’m not afraid of reporting, everything should be close to actual combat!”

"You are not afraid of death. I am afraid of the loss of the plane you have." The base leader glanced at him: "Fly according to the original plan, launch anti-ship missiles at an altitude of 20,000 meters and 80 kilometers away from the target. Target missiles and return!”

YJ-81 is a solid-engine anti-ship missile with a maximum range of only 40 kilometers. The range of an air-launched anti-ship missile is related to the launch altitude and speed. The higher the altitude, the greater the speed, and the farther the range. If it is launched from two When launched at an altitude of 10,000 meters at high-pressure sonic speed, the range will be increased to more than 60 kilometers.

 However, it is now required to launch at a distance of 80 kilometers. What does this mean?

This is obviously because they are afraid of damaging the warship. In fact, it is just a target missile and has no warhead at all. This is also a fear of danger.

Zhang Yongchao stopped talking. He may not care about his own life, but he can't care about his plane. For every pilot, he needs to care for the plane as much as he cares for his own life. Even if he doesn't care for his own life, he still has to. Take good care of the aircraft.

“Now, let’s discuss specific tactics.” The leader continued to issue orders.

On the majestic sea, warships are breaking through the waves and cutting through the thorns.

 The shapes of the two warships are full of modern feeling. Compared with the messy superstructures of the past, they appear very simple.

From the bow of the ship to the rear, there is a fold line, and the buildings above the fold line begin to shrink back. This simple method can play a very good stealth role.

 It's just that the shape of the superstructure extending over is slightly different. The 052B with four small shields looks taller, while the 052C with four large shields looks thicker.

 The two warships sailed in formation as if they were brothers.

“These two warships look good.” Wu Shengli stood on the bridge of 052C, looking at the sister ships, and said with emotion.

"Yes, our domestic shipbuilding technology has developed rapidly in the past ten years. Our two destroyers are enough to make Europeans envious."

Europe has long wanted to build air defense ships, but after so many years of doing so, it has not been done. Different countries have different needs, and the coordination of weapon systems is not easy. Later, they worked separately, and progress was still slow.

Twenty years ago, the East had just opened its door to the country, and the Western weapons we saw were all advanced. At that time, we even considered introducing Sea Dart missiles from the United Kingdom and equip them on the 051 destroyer, and even gave them the number 051S.

 Due to various reasons, the 051S project was ultimately aborted. For a long time, the Dongfang fleet was running naked. Once the navy was very envious of the West, now it is the West's turn to be envious of itself!

“Dad, when the warships are put into service in the future, we can go out more and show our advanced technology from the East to Westerners, so that the West will not keep discrediting us.” Qin Tao said.

 Many Western media have been reporting on the situation in the East with colored glasses. In their mouths, the East is backward. The East cannot even afford electricity and still uses kerosene lamps. The reports are one-sided.

Warships are not only weapons, but also a window to show one's strength to the outside world. Send warships out to the ports of other countries, let the citizens come to visit, and let them see that the warships built by the East are better than their own. Strong, so that the outside world can better understand the East.

At this time, after hearing Qin Tao's words, Wu Shengli smiled: "Taozi, are you thinking of the recent smear rumors on the Internet?"

Wu Shengli certainly knew about this matter. Those rumors regarded Wu Shengli as the big backer of the Mingzhou Group, saying that he protected his son-in-law and undertook various naval projects.

He is not afraid of investigations, and his integrity is not afraid of his shadow. Over the years, the Navy has relied on the Mingzhou Group to develop and grow. The old leaders are clear about the contribution of the Mingzhou Group to the Navy. This is not because the Mingzhou Group is taking advantage of the Navy, but because the Navy is taking advantage of the Mingzhou Group!

However, if these rumors spread, they will still have a bad impact on Mingzhou Group and him.

"No, it's just a trivial matter. Since there is an ignorant ant blocking the road, just step on it." Qin Tao said: "Dad, you should know that I said this so that Mingzhou Group can sell Let’s send more foreign trade warships.”

Sending out this kind of warship with four shields and letting the world see the world's second Aegis system will definitely promote the Mingzhou Group. The Mingzhou Group will gain higher prestige, and the sales of warships will also increase. Can go to the next level.

“But our navy will not allow this kind of warship to be sold.”

"This is just a propaganda method. Even if 052C is not sold, 054 can always be sold." Qin Tao said: "What we want to show to the outside world is the confidence of a strong motherland!"

 Some people are working hard to make the motherland strong, while others are sparing no effort to slander the motherland. No matter what time, there is no shortage of traitors.

 In the capital, in an Internet cafe near a university.

The cigarette **** was emitting wisps of green smoke, and a large part of it had been burned. Then, with the movement of the mouth, it fell to the bottom.

Pan Han, who had a sharp mouth and monkey cheeks, didn't bother to take the cigarette **** out of his mouth. Even though the smoke had made his eyes start to cry, he was still tapping the keyboard with his hands.

I don’t know how long it took, but he suddenly felt as if his surroundings had quieted down. When he raised his head, he found a person holding a camera, pointing it at his screen, and filming himself wildly.

“Hey, what are you doing?” Pan Han turned around in surprise.

 “You are Pan Han, right? Long live the domestic product of Internet Name Island.” Next to the camera, another man in a suit and ties said.

"Yes, it's me. What's wrong? Does it have anything to do with you?" Pan Han had a cigarette **** in his mouth and his words were unclear.

"I am a lawyer from the legal department of Mingzhou Group. You have made many inappropriate remarks on the Internet, which have seriously damaged the reputation of our Mingzhou Group. Therefore, on behalf of Mingzhou Group, I solemnly tell you that we have submitted a request to the court. A complaint has been submitted. You need to apologize to us for these inappropriate remarks, and then compensate us one million for reputational damage. It is estimated that the court summons will be sent to you soon, of course, it may be sent to you first. Your college.”

What?

Pan Han was shocked by these words. He didn't expect that Mingzhou Group would actually come to his door, asking for one million?

ah!

Pan Han suddenly exclaimed, without holding the cigarette **** in his mouth, it went directly along his collar and into his stomach. He was so burned by the cigarette **** that he grinned and quickly reached out to take it out.

The visitors had already turned around and left. Looking at their leaving figures, Pan Han's heart was beating violently.

Pan Han was born in a special family. His uncle ran to the other side of the country after the civil war. In the past few years, he came home to visit relatives, but he was envious of him. After that, he began to yearn for foreign countries more and more. After he was admitted to university, he even tried to get close to the international students in the university. Under their influence, he was full of yearning for the Western world. He was already a banana man with yellow skin and white heart.

Pan Han felt his legs trembling a little. One million is a huge sum of money for anyone! What if the money is still not paid? Do you want to spend your whole life in prison?

There are no old people in this era. If you don't pay back the money you owe, you can go in and squat. He took a few deep breaths, then opened ICQ and started asking for help in a special group there.

 Help, Mingzhou Group wants to sue me and ask me to compensate one million!

What are they afraid of? If they sue, they may not win!

 That's right, this time it's time to leave the Internet and show the dominance of the Mingzhou Group in the real media!

 Don’t worry, long live the island products, we are all supporting you behind the scenes!

Even if you lose the lawsuit in the end, we will find a way for you to collect the money! Besides, this lawsuit cannot be defeated!

The support in the chat group finally allowed Pan Han to regain his composure. He picked up half a cigarette, continued to light it, and started smoking.

At sea, Qin Tao didn't take this little ant seriously at all. The strength of the navy was his most important thing.

“Attention, we are about to reach the test sea area. The sea area has been cleared. Air Police 2000 is responsible for making judgments four hundred kilometers away.”

So far, the Navy does not have an early warning aircraft. This major test project can only be to lease the Air Force's Air Police 2000. This early warning aircraft rarely has the opportunity to monitor so many targets. It can just test the performance of the Air Police 2000. .

“052C has turned on the search radar!”

“052B has turned on the search radar!”

“Open the data link and transmit it to the rear in real time!”

Judgment not only depends on Air Police 2000, the Navy itself also has a way, that is, its own data link, which sends all air defense data back through the data link, and then performs synchronized judgment at the rear.

The antenna of the 517 meter-wave radar rotated.

This kind of antenna is quite special. It has a crossbar. The top and bottom of the crossbar are each equipped with four 90-degree vertical horizontal poles. This layout earned it the nickname of a clothes drying rack. However, there is also a horizontal pole on this horizontal pole. A small crossbar looks like a fish bone, so it is also called a fish skeleton.

From the outside, this radar seems to be very old, but the only thing that is old is its antenna and its internal circuit, which have been undergoing substantial changes.

 Specifically, Type 517 is developed based on the Jing-17H radar. It started in 1976 and was finalized in 1986. After the finalization, the performance has lagged behind. Therefore, domestic technicians worked non-stop and came up with the 517A radar. As for what is now stamped on the 052C destroyer, it is the further improved 517B radar. As for The direction of its improvement is, of course, its ability to fight against stealth machines.

However, until it was on board the ship, it had not fought against the J-31A that was coated with stealth coating. Therefore, the ability to detect stealth aircraft is still unknown for the time being.

 Now, it is a test for this radar.

The atmosphere in the bridge became tense. Wu Shengli asked curiously: "Aren't you going to turn on the phased array radar?"

“What we are simulating now is a patrol situation. We first use meter wave radar to detect, and only after the target is detected, the phased array radar will be turned on.” Qin Tao introduced: “This also saves some money.”

 What to save? The first one is to save power. This four-sided phased array radar consumes a lot of power. Even if the warship is matched and the power generation is increased, save some if you can, otherwise the warship will keep turning it on during the voyage. , stop running thousands of miles.

The second is to save life. The four-sided phased array radar antenna must have a lifespan. It is best to use it sparingly. There is no need to replace the T/R components when the warship is retired.

“Target found, five hundred kilometers away!” the radar soldier shouted.

 This is the advantage of meter wave radar! In addition to the benefits of power consumption, lifespan, etc., it also has a huge benefit, which is that it has a long detection range!

The longer the wavelength, the farther the detection distance at the same power. This is the iron law of radar. Just like in the previous competition in phased array radar technology, 14 chose S-band, while competitors chose C-band. As a result, the Navy used The solution adopted by the 14th Institute is because the S-band has a longer detection range. The navy must have a far enough detection capability.

Now, the search distance of the clothes drying rack of the meter wave radar is even further! High-altitude targets can be detected five hundred kilometers away. Even later, when meter-wave radar also adopted a phased array system, F-22s were even discovered at a distance of four hundred and fifty kilometers! (Some magazines say this, I don’t know whether it’s true or not.)

 “Main phased array radar is on!”

As the order was issued, Qin Tao seemed to hear the buzzing sound of the generator behind him. He knew that this was his illusion. However, with the activation of the four-sided phased array radar, a large amount of electromagnetic radiation was being emitted to the surrounding areas. Scanning, if you stand in front of the radar antenna at this time, you will probably get static electricity all over your body.

Nearby, on the 052B destroyer, the captain asked anxiously: "What's going on? Our radar hasn't found the target yet?"

“There is no report yet. The longest detection distance of our rotating phased array radar antenna is four hundred kilometers.”

  Just after the test started, they were already at a disadvantage, just because they did not use the ancient meter wave antenna!

Sun Xuewen, who was accompanying the ship, had a calm look on his face. He had already guessed this outcome. After all, they wanted to win based on cost-effectiveness. The performance was not the most advanced, but the cost was low. It was absolutely impossible for them to compete with the 052C. performance.

 Four hundred is four hundred kilometers. Anyway, such a long distance is just for viewing and nothing else can be done.

 “Four hundred and fifty kilometers!”

 “Four hundred and twenty kilometers!”

When the 052C observation target was 420 kilometers away, the rotating phased array radar on the 052B finally had a harvest!

“Target found! Wait for the next refresh to measure various data and pass it to the air defense missile system!”

 Their antenna is rotating, not fixed! Therefore, even if they find the target, it is impossible to obtain various information immediately. They must wait until the next time the antenna turns over, and then they can determine the target's speed and other information based on the comparison of the two data before and after.

Here, the 052C phased array radar has captured the target. The data processing system moves quickly to classify the T/R components and aim them at certain targets respectively. The data appears on the screen in an instant.

“The first batch to arrive are ten targets, respectively at an altitude of 20,000 meters and 15,000 meters. The targets are very clear, they should be fighter planes.”

Different targets have different radar echoes and different detection distances. If you want to detect them better, you have to mobilize more T/R components. Now, only a small number of T/R components are used, and it has been completed. The measurement of the target shows that it is a large target and the radar reflection wave is very strong.

“The meter-wave radar report found that there is a vague outline between the two batches of targets. It is not very clear. It may be a stealth aircraft!”

  052C warship has discovered the stealth target!

 The 052B destroyer here is anxious.

“What’s wrong? Haven’t we discovered the invisible target yet? If we don’t discover it in time during wartime, we will be beaten!”

 “Report, cannot be found for the time being!”

“Damn it, stop the radar and aim all the radar waves in that direction. I don’t believe I can’t find it!” The captain was anxious.

"No, doing this will cause us to lose the search for other airspaces. In this test, there will be a large number of targets flying from different directions!" Sun Xuewen immediately refused on behalf of the developer of the warship.

"We also have four small shields, which can detect the target a hundred kilometers away. Anyway, the interception target can only be fired within fifty kilometers. A discovery distance of one hundred kilometers is enough!" The captain couldn't swallow this breath. .
