Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 208: 102 Technology Survey

Northwest of Mission Hills, Longhua District, Shenzhen City.

The building here covers an area of ​​about two hundred acres, which is quite large. There are seven factory-like buildings inside, as well as a dozen small buildings with three or four floors. The walls are covered with green vines, and it looks like a An ordinary factory.

There is a sign hanging at the door that says "Shenzhen Huarong Textile Factory!"

Mr. Mu has some questions, what are you doing here?

Zhao Guoqing said: "Mr. Mu, put on your mask!"

"..."

Mr. Mu has been in the military for many years. As soon as he arrived at the door, he felt the difference here. Although the guard at the door was wearing casual clothes, his behavior was that of a soldier...

"this?"

Zhao Guoqing smiled and said: "102 involves many foreign-related matters, and some secret research is placed here!"

Mr. Mu nodded. With his rank, he also knew that a certain research institute under Mr. Zhao had obtained the official Chinese weapons certificate. They had this permission.

"Mr. Mu, come in!"

In an office with only a dozen people, everyone has a computer on their desk, and they look very busy.

The person in charge, Hao Mouzhi, said: "We are working on a terrain matching system!"

Mr. Mu asked: "What is the terrain matching system?"

Chief Hao said: "Leader, terrain matching is to input map information into the computer in advance, and then scan the terrain data through the radar on the aircraft and match it with the map information outline data to determine the location of the aircraft."

"..."

It may sound familiar.

"Leader, this is used for navigation of cruise missiles, aircraft and other aircraft!"

Cruise missiles, we can also build cruise missiles!

Zhao Guoqing said nothing and led Mr. Mu to the laboratory next door.

This is the laser guidance laboratory. Due to the many different methods of laser guidance, it is also divided into four different groups.

"The first way is to install the laser on the aircraft, and use the optical sighting system on the aircraft to hit the laser on the target and guide the bomb to fly to the target!"

"We can also set the laser generator on the bomb. It is similar to the terminal guidance of the R530 air-to-air missile. The laser actively guides. The advantage of this guidance method is that you can leave the bomb alone after it is thrown and the bomb will automatically guide. However, the disadvantage is that it is too expensive... …”

Laser is only one of the diversified guidance methods. In fact, laser guidance is greatly affected by weather, and laser guidance is not only used for precision guided bombs.

Research laboratories one after another, such as the infrared guidance laboratory, television guidance laboratory, optical guidance laboratory, and radar and microwave guidance laboratory, dazzled Mr. Mu...

Zhao Guoqing said to Mr. Mu: "These are basic research on guidance technology, and there is already a considerable scale of shelf technology!"

Mr. Mu is very happy. He knows the term "shelf technology" and these navigation and guidance technologies can be used directly.

"General Master Zhao, I really don't know, you have done so much..."

Where is this? I just looked at one building.

There are things going on everywhere in the thirteen buildings.

Building 02 is on the left side of Building 01. It is the same building with similar room settings.

The research room is relatively large, and each person has a computer on each table. The screen on the computer is different from the rows of data on Building 01 just now. This time the computer is full of images, and Mr. Mu can see it at a glance. is a three-dimensional image of the missile.

Zhao Guoqing said: "This is CAD software for designing aircraft. It is not very mature yet. The preliminary shape design can also be done with finite element analysis of each surface and local structural demonstration."

As for the overall aerodynamic analysis and vibration analysis, there is a bit too much thought. An IBM minicomputer simply cannot complete vector calculations of this magnitude.

Zhao Guoqing is not good at the aerodynamic shape design of missiles or servo flight control. He is good at avionics radar technology. He is also a novice in this field, but he has technical information on R530, Aspad and Monster Snake III. A better reference is not starting from scratch.

Teacher Xiao Zhao said with a smile: "We still have a thorough understanding of the technologies of these three missiles. We used computers to simulate the designs of these three missiles and basically figured out their design ideas. However, the low-altitude flight control of cruise missiles still needs more work. Give me some time!" "Not bad, not bad!" Mr. Mu said repeatedly!

Building 03 is the radar technology research building, and it is also the place where Zhao Guoqing feels most at home.

Jia Pengfei is an old acquaintance, and they have worked together when Zhao Guoqing first entered the 14th Institute.

"Director Zhao! President Mu!"

Zhao Guoqing nodded, and Mr. Mu looked at Jia Pengfei and said, "General Master Jia, why are you here?"

The two met on the xzk001 modification radar. At that time, Jia Pengfei was still in the 101 Institute and was the chief engineer of the project.

"I feel at ease following Director Zhao!" Jia Pengfei said with a smile.

Zhao Guoqing said: "Pengfei, don't be so stupid. You are always here to collect debts..."

"...Master Zhao, I'm not..."

Jia Pengfei said: "Mr. Mu, why don't you go to the testing workshop and have a look!"

"Already have a sample? Okay!"

The three of them came to the test workshop. This is a separate factory building. The layout inside is different from that of an ordinary factory building. There are no windows in the factory building, and the entire interior is covered with something similar to ceramic tiles. If there were not three headlights, It's going to be pitch black here.

In the middle of the factory building is a radar, which looks exactly like the radar mounted on the JH-7. The space in front of the circular antenna array is densely packed with sensors.

"It's all made of absorbing materials to prevent radar waves from leaking out. The space is small and the tests that can be performed are limited. The main purpose is to verify whether the radar wave sharpening calculation can correspond to the parameters we designed!"

Jia Pengfei handed the bottle cap-sized chip to Mr. Mu and said, "This is a new processing chip. Director Zhao pointed out to us the development ideas of radar anti-interference technology. We can add phase difference accumulation calculation and phase control to the data processing." On top of that, side lobe cancellation technology is added, and the transmitter adds rapid changes in pulse width to combat interference...

Mr. Mu, there is a cutting-edge new technology this time. With this new technology, the Air Force will no longer be able to see hundreds of false targets like last time..."

"Really?" Mr. Mu stared at Jia Pengfei, then looked at Zhao Guoqing.

Zhao Guoqing kicked Jia Pengfei and said, "I never promised you to keep a low profile. That's what I said!"

"..."

The new technology is polarization suppression of false target interference, or it can also be said to be polarization identification of deceptive false target interference.

This is a paper that Mr. Zhao published twelve years later in the original history. Most of the content was not made public before publication because it was confidential. And because of this paper, he was shortlisted as an academician of the American Academy of Engineering, which shows the importance of the paper. Heavy.

You must know that false target interference technology is a frequency shift interference technology based on DRFM digital radio frequency memory for radar constant false alarm detection and amplitude attenuation false target interference.

This new jamming technology from the United States also has the function of suppressing our own interference, making it impossible for radars to detect the existence of actual targets, and the US jammers themselves will not expose the targets.

Zhao Guoqing's plan is to establish a receiving signal model for targets and active false targets by receiving signals without changing the structure of the radar, and use the optimal polarization detection OPD algorithm, polarization whitening filter and tensor synthesis processing to improve radar detection. Target performance, no matter how awesome it is, it cannot be 100% successful.

"Theoretically, there is about an 80% chance of identifying the real target!"

"If three fighters approach the target from different angles, and if each other's avionics can exchange information, there should be a 99.2% probability of identifying the real target."

"..."

This probability is already very high. Mr. Mu shook his head and asked: "If we lock the target, can we attack the early warning aircraft?"

Zhao Guoqing nodded and said: "Within the range where air-to-air missiles cannot escape, early warning aircraft are much easier to fight than fighter jets."

Mr. Mu smiled and said: "80% is already very high. If one missile is not enough, then fire another missile. You will have the ability to fight back! Mr. Zhao, Mr. Jia, hurry up and demonstrate the new radar on the machine!"

"..."
