Chapter 650 The Vigorous Meter Wave Radar

  The wasteland village base.

   "Hey, what's going on today? J-31A is back again? Besides, it's still black?" Pilot Zhang Yongchao looked at the plane that appeared in the parking area and asked very curiously.

The pilots of the first batch of carrier-based aircraft have graduated, and they all boarded the 001 aircraft carrier. Zhang Yongchao belongs to the second batch of pilots. Like the first batch, they are also studying hard and training hard, striving to get on the warship as soon as possible and become qualified carrier-based aircraft pilots. .

Their usual training is either a trainer plane or a single-seat J-15. Although there were J-31A stationed here some time ago, they left Huangdi Village after the aircraft took off and landed on the aircraft carrier. There is no need to stay at the base anymore.

   Now, I didn't expect to see another J-31A, and it has been painted with a stealth coating. What does this plane suddenly appear, what does it mean?

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

   "Maintain the plane."

   "What about after maintenance?"

   "Let's fly."

   "What about after the release?"

   "Continue to take care of it."

  Zhang Yongchao shook his head helplessly. This is a chicken-and-egg answer, an endless loop.

   "Forget it, we have secrecy rules, don't inquire about what you shouldn't inquire about, hey, it seems that a Yunba flew over?"

   Yunba landed on the runway, the rear cabin door opened, and then, large boxes were unloaded inside, and a row of large characters were sprayed 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 direct everyone to unpack the box. After unpacking, Zhang Yongchao opened his eyes wide and looked at The drone inside: "Is this a coaxial inversion structure?"

  The navy has imported Lao Maozi's ship-borne helicopter, which has a coaxial reverse structure, is short and tall, and forms a sharp contrast with other helicopters.

The same is true for the plane in front of me. It is unmanned, so it does not have a cockpit. The whole body is like a short and thick airship. It has two rotors on its top and only two rudder surfaces at the tail. Tail rotor, this method makes the rear mechanical structure simple, and at the same time, the aerodynamic force is symmetrical, and the controllability is good, which is very suitable for unmanned driving.

   This is the drone that Capital University of Aeronautics and Astronautics flew for the first time in 1995. It has been improved and improved in the following years. Now, it has finally been used, and it has brought ten more! The R&D team is very excited.

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

   "Test the air defense system of our new warship. Our seagulls can fly low against the sea surface to see if the air defense system of the new warship can detect us." The visitor said.

   New warships, air defense systems? Zhang Yongchao immediately realized: "Our 052C is about to be tested!"

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

   "Got it, I'll go there right away!"

  The conference room at the base was lively. When Zhang Yongchao went in, he heard them all talking in low voices about the 346 radar, hundreds of targets, etc., which kept passing into 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 system of our 052B and 052C destroyers, we need to dispatch ten aircraft As a high-altitude target approaching the warship, we plan to dispatch five J-15 and five trainer planes to fly at altitudes of 20,000 meters and 15,000 meters respectively."

   "Report, will that J-31A also be mixed in our formation?" Zhang Yongchao raised his hand.

"It's not your turn to speak yet!" The leader gave Zhang Chao a dissatisfied look. No matter which batch, there will be skilled pilots, not only with superb flying skills, but also with a bad temper, just like this Zhang Chao, who doesn't follow the discipline, actually interrupts when the leader is speaking!

"J-31A will fly at an altitude of 18,000 meters, and will be mixed between our two formations. This arrangement is to better confuse the opponent. At the same time, each of our five fighters carries two Eagle Strike 81 anti-ship missile target.”

What?

   Now the pilots couldn't help cheering.

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

   Now, they finally have a chance to hit the missiles!

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

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

"what is the problem?"

"In my opinion, the range of the YJ-81 missile is too short. We need to fly 50 kilometers away from the target to launch, and our route is limited to high altitude. This is very inappropriate. I suggest that we fly into the , Only in this way can we better simulate actual combat!"

"Ultra-low altitude? According to the exercise arrangement, ultra-low altitude, targets within 50 kilometers belong to the shooting zone, and the target warship can launch missile attacks without hesitation! Zhang Yongchao, do you dare to fly there? You are not afraid of being shot down by Hongqi Nine ?”

   "Report, I'm not afraid, 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, at an altitude of 20,000 meters, when the target is 80 kilometers away, launch the anti-ship missile Target missile, and return home!"

The YJ-81 is an anti-ship missile with a solid engine, and its maximum range is 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. When launched at an altitude of 10,000 meters with high-pressure sound speed, the range will be increased to more than 60 kilometers.

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

   This is obviously because they are afraid of hurting the warship. In fact, it is just a target bomb, and there is no warhead at all, so it is also afraid of danger.

Zhang Yongchao stopped talking, he could not want his own life, but he had to care about his own plane. For every pilot, he needs to love the plane like his own life, even if he doesn't love his own life, he must Love the plane.

   "Now, let's discuss specific tactics." The leader continued to issue orders.

  On the magnificent sea, warships are breaking through the waves and overcoming obstacles.

  The shapes of the two warships are full of modern feeling. Compared with the previous chaotic superstructure, they appear very simple.

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

   However, the shape of the superstructure extending past is somewhat different. The 052B with four small shields looks taller, and 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, looked at the sister ships, and said with emotion.

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

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

  Twenty years ago, the East just opened its doors, and all the Western weapons it saw were advanced. At that time, it even considered introducing Sea Javelin missiles from the United Kingdom to equip it on the 051 destroyer, and even gave it a 051S number.

  Due to various reasons, the 051S project was ultimately aborted. For a long time, the Eastern fleet has been running naked. The navy used to envy the West very much, now it is the West's turn to envy itself!

   "Dad, when the warship is commissioned in the future, we can go out more and show our advanced technology from the East to the West, so that the West will not continue to discredit us." Qin Tao said.

  Many Western media have been reporting the situation in the East with colored glasses. According to them, the East is backward, and the East can’t even afford electricity, and still uses kerosene lamps. The reports are all one-sided.

Warships are not only weapons, but also a window to show their strength to the outside world. Move the warships out to the ports of other countries, let those citizens come up 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 Dongfang.

  At this moment, upon hearing Qin Tao's words, Wu Shengli smiled: "Taozi, do you think of the recent smear rumors on the Internet?"

   Of course Wu Shengli knew about this matter. Those rumors made Wu Shengli the big backer of the Mingzhou Group, saying that he was protecting his son-in-law and undertaking various naval projects.

  He is not afraid of investigations, and his body is not afraid of being crooked. Over the years, the navy has grown and grown by relying on the Mingzhou Group. The contribution of the Mingzhou Group to the navy is clear to the old leaders. This is not because the Mingzhou Group took advantage of the Navy, but because the Navy took advantage of the Mingzhou Group!

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

"No, it's just a trivial matter. Since there are ignorant ants blocking the way, just trample it to death." Qin Tao said, "Dad, you should know that I say this so that Mingzhou Group can sell More foreign trade warships are going."

Launch this kind of four-sided shield warship and let the world see this second Aegis system in the world. It will definitely be promoted to Mingzhou Group, and Mingzhou Group will be able to gain higher prestige, and the sales of warships will also increase. Can go to the next level.

   "However, our navy will not allow this kind of warship to be sold."

   "This is just a means of propaganda. 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 for the strength of the motherland, and some people are sparing no effort to slander the motherland. No matter when, there is no shortage of traitors.

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

  The **** of the cigarette was emitting wisps of green smoke, and it had burned a lot, and then fell to the bottom during the movement of the mouth.

  The monkey-cheeked Pan Han didn't care to take the cigarette **** out of his mouth. Even though the smoke had already made his eyes start to water, he was still typing on the keyboard with both hands.

   I don’t know how long it took, but he suddenly felt that his side seemed to be quiet. When he looked up, he found a person carrying a camera, aiming at his screen, and shooting himself frantically.

   "Hey, what are you doing?" Pan Han turned his head in surprise.

   "Are you Pan Han? Long live the online name Dao Guoguo." Beside the camera, another man in a suit and leather shoes said.

   "That's right, it's me. What's the matter, does it have anything to do with you?" Pan Han spoke indistinctly with a cigarette **** in his mouth.

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

What?

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

ah!

  Pan Han suddenly let out a cry of surprise, without the cigarette **** in his mouth, he burrowed directly into his stomach along his neckline.

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

Pan Han was born in a special family when he was a child. His uncle ran to the other side after the civil war. He visited relatives and went home a few years ago, but he was envious. After that, he began to yearn for foreign countries even more. After being admitted to the university, he even tried to get close to the foreign students in the university. Under their influence, he was full of yearning for the western world. He was already a banana man with a yellow skin and a white heart.

  Pan Han felt his legs tremble a little, one million is a huge sum of money for anyone! What if the money is not paid? Do you want to spend your life in prison?

  In this day and age, there is no Lao Lai. If you don’t pay back the money you owe, you go in and squat down. He took a few deep breaths, then opened ICQ, and started asking for help in a special group inside.

  Help, Mingzhou Group wants to sue me and ask me to pay one million in compensation!

   What are you afraid of, they sue, and they may not win!

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

  Don't worry, long live the island country products, we all support you behind the scenes!

  Even if you lose the case in the end, we will find a way for you to raise the money! Besides, this lawsuit can't be lost!

  The support in the chat group finally restored Pan Han's calm. 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, the test sea area is about to arrive, the sea area has been cleared, and Air Police 2000 is responsible for the judgment four hundred kilometers away."

So far, the navy has no early warning aircraft. The major test project this time can only be the Air Police 2000 leased from the Air Force. 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 activated the search radar!"

   "052B has activated the search radar!"

   "Turn on the data link and transmit it to the rear in real time!"

  The judgment does not only depend on the Air Police 2000, the Navy also has its own method, that is, its own data link, through which all the air defense data is sent back, and then the simultaneous judgment is made in the rear.

  The antenna of the 517-type meter wave radar rotated.

This kind of antenna is quite special. It has a horizontal bar, and the horizontal bar is equipped with four 90-degree vertical horizontal poles. This layout gives it the nickname of a clothes rack. However, there is a A small horizontal bar looks like a fish bone, so it has won the title of a fish skeleton.

  From the outside, this kind of radar seems to be very old, but only its antenna and its internal circuit have been greatly changed all the time.

   Specifically, the Type 517 was developed on the basis of the Jing-17H radar. It began in 1976 and was finalized in 1986. After the finalization, the performance has fallen behind. Therefore, the domestic technicians have been working non-stop, and they have produced the 517A radar. As for the 052C destroyer, it is a further improved 517B radar. As for The direction of its improvement, of course, is the ability to fight against stealth aircraft.

  However, until boarding the ship, there was no confrontation with the J-31A coated with stealth coating. Therefore, the ability to detect stealth aircraft is still unknown for the time being.

   Now, it is a test of this radar.

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

   "We are now simulating a patrol situation. We first use the meter wave radar to detect, and the phased array radar will not turn on until the target is detected." Qin Tao introduced: "This also saves some money."

   What to save? The first one is power saving. This four-sided phased array radar consumes a lot of power. Even if the warship has been matched to increase the power generation, it can save as much as possible. Otherwise, the warship will keep driving it during the voyage. , Don’t run thousands of nautical miles.

  The second is to save life. The four-sided phased array radar antenna must also have a life. It is best to save it and not need to replace the T/R components when the warship is decommissioned.

   "The target is found, the distance is 500 kilometers!" The radar soldier shouted.

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

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 phased array radar technology competition, 14 chose the S-band, and the competitors chose the C-band. As a result, the Navy used The plan of the 14th Institute is because the detection distance of the S-band is longer. The Navy has to have a detection capability far enough away.

   Now, the clothes drying rack of the meter wave radar, the search distance is even further! High-altitude targets can be found at a distance of 500 kilometers. Even in the future, after the meter wave radar also uses the phased array system, F-22 is even found at a distance of 450 kilometers! (Some magazines said, I don't know if it is true or not.)

   "The main phased array radar is on!"

As the order was issued, Qin Tao seemed to hear the humming sound of the generator behind him. He knew that this was his own illusion. However, with the activation of the four-sided phased array radar, a large amount of electromagnetic radiation was radiating to the surrounding area at this time. Scanning, if you stand in front of the radar antenna at this time, it is estimated that the whole body will have static electricity.

   Nearby, on the 052B destroyer, the captain asked anxiously: "What's going on? Has our radar not found the target yet?"

   "Report, not yet, the farthest detection distance of our rotating phased array radar antenna is 400 kilometers."

   Just started the test, and it was already at a disadvantage, just because they didn't use the ancient meter wave antenna!

Sun Xuewen, who accompanied the ship, had a calm face. He had already guessed this result. After all, they want to win, relying on cost performance. The performance is not the most advanced, but the cost is low. It is absolutely impossible for them to compare with 052C. performance.

  Four hundred is four hundred kilometers. Anyway, such a long distance, just to see, and can't do anything else.

   "Four hundred and fifty kilometers!"

   "Four hundred and twenty kilometers!"

  When the 052C observed the target at 420 kilometers, the rotating phased array radar on the 052B finally paid off!

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

   Their antennas are rotating, not fixed! Therefore, even if they found the target, it was impossible to obtain all kinds of information immediately. They had to wait until the next time the antenna turned over, and then they could determine the target's speed and other information based on the comparison of the two data before and after.

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

   "The first batch of ten targets arrived, at altitudes of 20,000 meters and 15,000 meters respectively. The targets are very clear and should be fighter planes."

Different targets have different radar echoes, and the detection distance is different. If you want to find 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 is very strong.

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

  052C warship has discovered a stealth target!

  The 052B destroyer here is in a hurry.

   "What's the matter? Haven't we found that stealth target yet? If we can't find it in time when it comes to war, we will be beaten!"

   "Report, temporarily unable to find it!"

   "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, if we do this, we will lose our search for other airspaces. In this test, there will be a large number of targets flying from different directions!" Sun Xuewen immediately expressed his rejection on behalf of the warship's developer.

"We still have four small shields, which can detect the target at a distance of 100 kilometers. Anyway, the interception target can only be fired within 50 kilometers. A detection distance of 100 kilometers is enough!" The captain couldn't swallow this breath. .
