Chapter 213 Feast

   Sunburn is not a great weapon against aircraft carriers. Its range is too short, and if you charge up, you will die.

If you want to improve, there is still a long way to go to fiddle with the Eagle-12. Now it is good to be able to imitate it. Now the domestic industrial technology has developed very fast. It can still be imitated.

Missile boats rely on their invisibility to approach the enemy's aircraft carrier, and then launch such a big guy. There should be some hope. Sufficient speed and altitude, so its range will increase a lot.

   Of course, missiles are not enough.

Qin Tao pointed to a spherical cylinder at the top of the bridge, and said to everyone: "That thing is Lao Maozi's famous ore-ME (Mineral-ME radar, nicknamed the music station by the West.) radar , we have to imitate this radar mapping. In the future, our anti-ship missiles can use it to provide guidance. Even if our Haiying No. Use it to guide."

   "Leave it to us at 724!" Someone stood up immediately.

  At present, there is only Haiying 8 with a range of 40 kilometers in China, so there is no big problem with the guidance of anti-ship missiles. With this range, the warship's own sea search radar can find the target.

   But no matter how far away, due to the curvature of the sea, the enemy warships seventy or eighty kilometers away have already hidden below the sea level that the own warships can see.

  So, when the range continues to increase, we have to find a way.

  Ordinary warships use ship-borne helicopters. Standing high and seeing far away, as long as the helicopter flies up, it can see farther places, and it can make the target appear in its original shape. The helicopter will lock the target and at the same time provide relay guidance to the missile.

  However, when the helicopter flies, it also means that it will appear in the field of view of the opponent's air search radar. If the opponent's anti-aircraft missile range is far enough, the helicopter will also encounter danger.

  Lao Maozi's radar adopts a new method, which is the atmospheric waveguide effect that all military fans love to talk about. The radio waves emitted by ordinary radar are reflected back when encountering obstacles, and they all propagate in a straight line. So, is air an obstacle?

Under normal circumstances, the reflectivity of the atmosphere to microwaves is very small, but in some special cases, under the comprehensive influence of sea surface water temperature, air temperature, cloud height and other conditions, the phenomenon of atmospheric evaporation waveguide will appear near the sea surface, and the low-altitude atmosphere at sea level It will greatly increase the refractive index of some electromagnetic waves in the range of 1GHz-100GHz.

  The sea level and the upper atmosphere are closed to form a pipe. In this pipe, qualified radar waves are constantly reflected up and down, and advance alternately. (Tsk tsk, the metaphor.)

After Lao Maozi discovered this phenomenon, he conducted a lot of research, and then made this advanced radar, which can be said to be unique. In the case of the existence of atmospheric waveguide effect, the maximum search distance of its active search radar module can be Up to 250 kilometers.

  If it only has this search distance, it’s not too bad. What’s more, although it has been reflected many times, its accuracy is still quite high. Its error for frigate-sized targets does not exceed 50 meters!

   Therefore, it is not only a sea search radar, but also a fire control radar, which can completely transmit the captured data to the missile to complete the launch preparation.

  An error of 50 meters is nothing at all, because almost all anti-ship missiles have active radars. When they are near the target, they can turn on the radar to find the target by themselves. Not to mention 50 meters, 500 meters is nothing.

  It can also track 30 targets at the same time, and even initiate fire control level differential illumination on multiple targets at the same time within the line of sight.

  In addition to this kind of sky-defying ability, this kind of radar also has another ability, which is to work passively.

If there is a warship on the opposite side, if you turn on the radar search, it will radiate radar waves everywhere, and it will be received by the passive interception module installed on this ore-ME radar, because it can cover I/G/E/F / D-band radar radiation source, in passive mode, it can laterally locate the source target at a maximum distance of 450 kilometers.

   At this time, it cannot detect the distance of the target, but it can use the "binaural effect" to calculate the distance through the maneuver of the ship. (First drive to a place, measure, then drive to another place, continue to measure, and calculate according to the principle of triangle.)

This kind of radar is simply a timely rain for the motherland's navy. Qin Tao's 051C destroyer also plans to be equipped with this kind of radar equipment. Now, it can be handed over to relevant units for surveying and mapping imitation. It's a fake version.

   "We promise to complete the task!" The people in Institute 724 puffed up their chests.

   "Well, two years at the latest." Wu Shengli said.

  In terms of electronic technology, the country is already better than Lao Maozi, so it is not a problem to imitate it within two years.

  At this time, the dismantled mast has been hoisted down. Looking at the back-to-back flat-panel antennas on the mast, Qin Tao said: "This MR710 radar is also a key project that needs to be imitated by our domestic related units."

   "Leave this project to our 14th institute." Ben's old voice sounded: "We should be the best at doing this."

  When the meeting was held in the capital, Mr. Ben was very interested in the proposal proposed by Qin Tao. When he saw the back-to-back planks on the mast, he was even more surprised.

  At that time, he just thought it was difficult to obtain this kind of radar, but now, this thing is in front of him. For a research institute like theirs that specializes in radar, it is simply a piece of cake.

   "For you, it will take a year to imitate it." Qin Tao said: "Moreover, the area should be larger and the operating power should be higher, so that it can search farther."

   The requirements for the 14 institutes are of course more stringent.

"After this radar comes out, it should be able to replace our 381A radar, and for a long time, it will become the main force of our navy's sea-to-air search radar." When Wu Shengli said this, the people present were stunned again. .

   "This waveguide technology radar, replacing our phased array radar?"

   "From a technical point of view, it seems to be backward, but from the perspective of stability and reliability, there will definitely be progress." Wu Shengli said: "At present, we have solved the problems of reliability and stability first."

  Actually, there are domestic back-to-back radars, and they have been installed on the No. 132 destroyer for testing. This is the 381 A radar. However, it has been installed since 1983 and is still being tested, because there are too many problems with this radar.

This radar is of great significance and opened the phased array era of the motherland's navy. Of course, it is not an active phased array radar using T/R components, but a passive phased array radar using ferrite phase shifters. Equipped with frequency synthesizer and frequency-agile anti-jamming technology, it has a peak output power of 1 megawatt.

  However, in addition to being installed on destroyer No. 132, that is, in the late nineties, it was installed on No. 167, and then disappeared without a trace. On the contrary, the domestically-made top plate imitated from Lao Maozi, that is, the 382 radar, is used on many warships. Even when the 167 was improved in the mid-term, the 381 radar was removed and replaced with a 382 radar. (Some sources say that it was done by the Seventh Academy, and some say it was done by the 14th Institute. Ignore it, and put it on the 14th Institute.)

   On the way back, Wu Shengli had already discussed with Qin Tao many times that the imitation of these radars would allow the navy of the motherland to achieve a leapfrog development, so this step must be taken!

   No matter how poor the navy is, we must squeeze out funds to carry out these projects. Taking advantage of the rare opportunity now, we can improve the strength of the navy's equipment as soon as possible!

  The over-the-horizon ore-ME radar, coupled with this advanced roof radar, can make the navy reach the international mainstream level in these equipment fields!

  The Shikili missile system at the back has also become a complete set. On this basis, imitating the domestic model can greatly improve the navy's air defense level! In the future, it will be matched with Hongqi 9 and Hongqi 7, so that short-range, medium-range and area air defense are all complete!

   You have to do it even if you sell it!

   "Leave us the whole set of Shijili air defense missile system." The expert from Huating Academy of Aerospace Technology said.

"The plate slot array antenna array and the serpentine waveguide feed technology are used here, which reduces the processing difficulty and improves the performance. Lao Maozi is so smart, why didn't we think of it before?" At this moment, Mr. Ben He interrupted the expert's words and became emotional.

In the past, we could only look at photos. Even the high-definition pictures taken by the West could not capture specific details. Therefore, no one knew what was so weird about this flat-panel antenna, and even according to its flat-panel shape, Some laymen think he is phased array radar.

On fighter jets, the West has begun to use a large number of flat-panel slot antennas, which can effectively improve the ability to radiate electromagnetic waves and increase the performance of fighter radars. However, this requires high-precision processing technology, and the slots are all in proportion to the wavelength. Open, there is nothing wrong with it.

  The old man can't do it. The Su-27 is good enough. It still uses the outdated inverted antenna, that is, the inverted pot lid, which causes the radar to weigh more than one ton, which greatly limits the combat effectiveness of the Su-27.

  Navy also don't need flat plate slot radar antenna, but they use a tricky way.

  They made a waveguide out of aluminum alloy material, and opened a variable-slope slot on the narrow wall of the waveguide. This waveguide is fed by a power divider made into a serpentine waveguide. By changing the operating frequency, the phase relationship of each element of the array also changes, and the direction of the lobe changes accordingly. Therefore, this flat panel antenna can achieve the effect of scanning.

   Smart, really smart!

   Only when you get the real thing of Lao Maozi can you analyze the principle inside, and then it will be like enlightenment.

  Although Lao Maozi's precision machining technology is not as good as that in China, Lao Maozi's system integration ability is really strong!

  This serpentine waveguide system with coupling holes is also very simple. It is directly connected by a straight waveguide and a 180-degree curved waveguide. With our own technical level, it can be imitated in minutes!

Of course, for a radar, there are many difficulties that need to be overcome, and the radar antenna is only one of them. Others include processing systems, high-power transmitters, especially the traveling wave tubes inside, etc., but , These technologies are in the 14 institutes, so it is not a problem. They have already created a big guy like a strategic early warning radar.

  It’s okay to just imitate. They have to understand the technology and then improve the imitation, so that this kind of radar has a longer search distance and more batches of detection targets.

   Various tasks are being assigned continuously, and the researchers assigned to the task can't wait to go in and dismantle things. Fortunately, most of Lao Maozi's weapon systems are separated, so there will be no dismantling by mistake.

  Until dawn, everyone was busy. Qin Tao really couldn't hold on any longer. He looked at Wu Shengli, whose eyelids kept fighting, and said to him, "Leader, do you want to take a rest?"

   In front of so many people, Qin Tao is still called a leader, and it is not suitable to be called a private title. Even if many people know the relationship between them, that won't work.

"You have to remember, it's up to you to dismantle, and you will dismantle it. If you dismantle it wrong, give it back to me. If someone dismantles too much to hide something, don't blame me for being rude!" Wu Shengli said: "The demolition is finished. , put them aside, and wait until we finish counting before taking them away."

   After speaking, Wu Shengli walked out.

   "Dad, I'll show you our new house." Qin Tao said.

  Zhao Ling also followed, and she was in high spirits.

Hearing what Qin Tao said, Wu Shengli nodded: "Hmph, I didn't even hold a ceremony for the wedding, and just ran out to travel and get married. During this time, I don't know how many people laughed at me. Fortunately, you got it back, right?" Missing good things is like blocking their mouths, if they dare to speak again, I will choke them to death with good things."

  Wu Shengli is joking. He is very open-minded and will never interfere with his children's affairs. However, he still looks forward to visiting the future residence of his daughter and son-in-law.

   "By the way, do you want to change Xiaoling's position?" Although Wu Shengli was talking about Zhao Ling, he looked at Qin Tao.

In the past, Zhao Ling was a representative of the army, and she often ran around with her, all of which were orders from Wu Shengli. Now, Zhao Ling and Qin Tao are married, one is the person in charge of the group, and the other is a representative of the army. Although the two of them are still innocent at work, they will always be gossiped about.

   "Okay, Xiaoling can retire from the army, and then transfer to our shipyard, and be my secretary." Qin Tao said: "In the future, our company will be restructured. I will be the president and Xiaoling will be the chairman."

   Ordinarily, this can be considered a normal transfer.

  However, Zhao Ling shook her head.

  When she shook her head, both Qin Tao and Wu Shengli were taken aback.

   "Why, you don't want to?"

"At present, for our navy, the weakest point is still the air defense." Zhao Ling said: "For short-range point defense, we have the Sea Rattlesnake, and for area air defense, we have the imported S-300 and the domestic model developed by ourselves. However, in terms of medium-range air defense, there is still a blank. Our Hongqi-61 has poor performance and cannot meet the future needs of the navy. Now, since we have obtained a full set of Shijili air defense missile system, we have also begun to fully imitate it This anti-aircraft missile, so, I want to participate in this project!"

  Zhao Ling's words were resounding, but Qin Tao's face was ugly.

  What, you want to go back to your old job? what about me? I just got married, you want me to be a monk?

  I still think that I can go home and sleep with my wife every day in the future. It is justifiable, but you are so good, you are leaving?

   "Xiao Ling, our air defense system is indeed still weak, but we don't lack you alone. If you stay in the shipyard, you can also contribute to national defense." Wu Shengli said.

Zhao Ling shook her head: "Dad, you don't know, when I stepped on the Type 956 destroyer for the first time and saw the Shijili air defense missile on it for the first time, I already had a strong feeling, as As a technician engaged in anti-aircraft missiles, I have a special feeling for this missile, but the first time I got it back was only one missile. For us, it is of little reference. Now, we have moved Back to the entire anti-aircraft missile weapon system, the surveying and mapping imitation work will definitely start quickly, and I hope to participate in this project."

Zhao Ling's attitude is very firm: "Even if our regional air defense missile system is mature, these missiles can only be used on our large domestic warships. Now our navy has a weak foundation and cannot equip a large number of large warships. After all, Shikili is a medium-range air defense missile that can be installed on our medium-sized warships. For our navy, this missile system is more important. I want to contribute to our navy and build our The navy's air defense umbrella."

   "Xiao Ling, since you are so determined, then..." Wu Shengli looked at Qin Tao hesitantly. After all, this matter depends on Qin Tao's attitude.

   "Of course we have to support it." Qin Tao said: "Anyway, the Huating Aerospace Technology Research Institute is not far from us. Our shipyard also has a branch there, and I will often go there in the future."

Qin Tao must support him. He remembers very clearly that when Zhao Ling saw Shi Jili for the first time, the gleam in her eyes flickered. Zhao Ling really wanted to do this project, so he couldn't hold back .

   Anyway, isn't it Huating? If he wants his wife, he can drive there anytime.

  Zhao Ling's eyes were full of emotion: "Brother Tao, thank you for your understanding and support."

"By the way, Dad, I have some ideas. I'm embarrassed to say them in front of so many people. I'll report them to you alone now." At this time, the three of them were still walking towards the family building, and Qin Tao followed his own The idea came down.

"explain."

"Domestic military expenditures are already tight, but there are still many and complicated project models. I suggest that all other medium-range missile models under development should be stopped, and all efforts should be made to imitate this Shikili air defense missile system. Instead of thinking about those If it is immature, it is better to imitate the model that is now fully mature."

  The navy has been struggling with air defense for a long time, and domestic scientific research institutions are also constantly developing it.

  In 1966, the navy's first type of air defense frigate 053K began to enter the preliminary design. In the second year, the supporting Hongqi 61 ship-to-air missiles began to be developed. However, based on the technology at the time, it was not easy to develop land-based anti-aircraft missiles. After boarding the ship, it was quite difficult to overcome the influence of ship swing, vibration, temperature and humidity changes, and salt spray corrosion.

In addition to the special background of that era, until 1975, Hongqi 61 began to be tested on the ship. This experiment lasted for more than ten years. When Qin Tao traveled here, the navy was still testing and modifying Hongqi 61. Finally, it was installed on the 053H2G frigate.

  It took ten years to hone their swords, but this red flag 61 has been tossing for more than 20 years.

  However, the superiors also knew about the problem of Hongqi 61, so they were also developing a follow-up model. In March 1979, the Hongqi 63 medium and low-altitude air defense missile project was established. A hard requirement for this missile is that it must be able to effectively intercept cruise missiles.

  However, after entering the 1980s, as the country opened up and good things were imported from abroad, this missile was also dismantled and began to imitate foreign models.

One of them is the Hongqi 64. This is because the country has imported the Italian "Aspide" air-to-air missile. This missile is developed from the American-made Sparrow air-to-air missile. What is more important is the seeker technology, or decided to develop a new type of short-range air defense missile on this basis. In 1988, the development of Hongqi 64 officially started.

  Although this kind of missile is very advanced, after all, it requires high processing technology, which is completely different from the difficulty of imitating Lao Maozi's five big and three rough products.

There is also an imitation of this kind of air-to-air missile, which is the Thunderbolt-11. Because the imitation was not smooth, no matter whether it is the Thunderbolt-11 or the ground-based air defense missile, they were successfully imitated at the beginning of the new century. As a result, they were not equipped with much force.

Because by that time, there were already better models in China, and the Thunderbolt-12 air-to-air missile guided by active radar had also come out, and the Thunderbolt-11 was outdated. There is no equipment in the country at all.

  Now, there is no need to waste these funds.

  The other one is Hongqi 65.

  In July 1983, the Navy decided to develop the second-generation Type 052 destroyer. In September of the same year, the development of the medium-range air defense missile Hongqi 65 supporting the Type 052 began. Since the introduction of sea javelin missiles was being demonstrated in China at that time, this Hongqi 65, on the basis of inheriting the aerodynamic shape of Hongqi 4, absorbed the experience of "sea javelin" in terms of guidance stations and command systems.

  These plans are not going well. Now that Shi Jili is here, they should all stop. However, this is ruining the jobs of many units, and Qin Tao can't say it on the spot.

"Well, you are right. We will do our best to imitate Shi Jili, and we will give up everything else. We have to give an official number to this new air defense missile system. If it is common to the Air Force, it seems to be It's Hongqi 16's turn."
