Military Industry of Great Powers: Build the Strongest Flanker

When Zhao Guoqing came to Lucheng, he first went to the 14th family building to visit his parents. Yang Qing also came back. I don't know if it was because of motion sickness. He vomited all the way. When he arrived in Lucheng, his face was pale.

"what happened?"

“I don’t want to eat, and I’ll throw up as soon as I get in the car!”

"..."

It can’t be possible!

Well, Zhao's mother, who was a little suspicious, took Yang Qing to the hospital for examination, and Zhao Guoqing first met with Director Gao Changming.

It’s been a year since we’ve seen each other, and I’m filled with emotions!

Gao Changming said: "We have been working on the digital array synthetic aperture radar for two years. We have invested 300 million yuan, but there has been no response at all. The team discussed it and there was a strong call to stop the project. Now everyone is working on it. Controlled array radar..."

Zhao Guoqing shook his head and said: "It's only three hundred million. Whoever objects, let them check foreign newspapers. The United States has invested almost tens of billions of dollars in this. The technical difficulty of synthetic aperture radar is how to achieve high resolution." rate imaging, in fact, its essence is just an ordinary radar, and what we study is its echo signal processing!"

Why did Teacher Xiao Zhao let the 14th Institute to develop synthetic aperture radar? Firstly, 14th Institute was not short of money. Later, the technologies are similar. Through the research of synthetic aperture radar, we can get a glimpse of the way of radar anti-interference and strong electronic countermeasures. Not just synthetic aperture radar, but modern early warning radar and electronic jamming cabin!

Director Gao sighed and said: "It would be great if you were here. We all still have a backbone. Now that you have gone to sea, they are like headless flies, not knowing which direction to develop..."

Gao Changming also knows that Zhao Guoqing is different now. With a net worth of tens of billions, will he still look at the salary of several hundred yuan a month from 14 universities? Thinking of this, Gao Changming shook his head.

The plight of R\u0026D institutes 101 and 14 is obvious, but what about other places?

The 317 Institute studied the use of phased array radar on infantry fighting vehicles, and problems also occurred.

After adding dozens of transmitting antennas, the beam changes completely. On the circuit board, there is a problem with the transmission of high-frequency signal current between chips.

You must know that communication between chips is also represented by physical current. High-frequency current can excite electromagnetic waves. If no measures are taken during the transmission process, the current signal will surge back and forth between the chips, causing the chip to be unable to work at all.

"Why is it possible to add a 30-ohm resistor to the XKZ001 radar? Now that the frequency has increased by 10Mhz, why can't it be sufficient to add a 10-ohm resistor?"

The General Staff is concerned about both the Air Force and the Army. At Factory 317, Director Liu heard too much about the big problems caused by these little things.

At this time, Director Liu would never tire of telling others about painting phosphor powder on the glass of light-emitting semiconductors.

"There are some small things that don't look very technical, just like brushing phosphor powder on glass. It's simple. How do you make the two materials combine well? How do you ensure the thickness of the phosphor powder? How many nanometers are there? ...It's very thin...The method Director Zhao thought of can be done without advanced equipment...Even a layman like me feels that there is a lot of knowledge in it!"

In the final analysis, basic research is still insufficient, and the understanding of high-frequency weak currents is not enough. The current weak current circuits are only tens of megahertz. If the frequency rises to several gigahertz, the circuit will be different.

It's almost the same as the difference between ordinary network cables and Category 5e network cables, what are the shielding and noise reduction measures?

The more contacts you have, the richer your technical accumulation will be. This is a benign process.

Zhao Guoqing was not worried. At this time, he stood at the door of Institute 101 and looked at this young research institute, which he had built from scratch.

Most of the key number 57 people are no longer in the 101st institution.

Du Chuming said: "There are currently 3,172 scientific researchers in Institute 101 from top to bottom, including 452 with senior professional titles, and intermediate... 99% of them have bachelor's degrees... Nationally speaking, it cannot be said to be the largest, but the proportion of highly educated people and high professional titles is second to none even in the country..."

Zhao Guoqing nodded, Institute 101 is now very strong!

Du Chuming took Zhao Guoqing to various research laboratories.

"The progress of research and development is much slower than when you were here. There are no decent results yet. National Day, I am under a lot of pressure. I can't bear this burden at all. I still need to be the director of 101." sit!"

As Du Chuming expected, Director Xiao Zhao shook his head and refused.

"Du Ting, I have also established a research institute in Shenzhen City. If you are willing, our two research institutes can cooperate!"

Du Chuming shook his head and said: "Shenzhen City and Lucheng City are thousands of miles apart. Even cooperation is very difficult!"

Zhao Guoqing smiled and said: "Shenzhen City will have fiber optic connections in two months. The leaders there also pay more attention to us and have set up two dedicated lines for us. From now on, cooperation can be done on the Internet. It's not as easy as you imagine." in trouble!"

Institute 101 was among the first batch to receive optical fiber, but there were too few Internet applications at this time. The state bought several servers from IBM and set up three FTP service stations. It also commissioned the American company McKinsey to set up two FTP service stations. mail server.

The so-called applications are sending emails and downloading data from FTP websites. There is no web server yet, and there is no Internet content provider. There is really nothing to do online.

That's what Du Chuming thought.

"Institute 101 is also connected to the Internet. I think this thing is not as convenient as making a phone call!"

Zhao Guoqing said: "That's what you think, do you know what I'm doing now?"

"..."

"do what?"

Zhao Guoqing said: "I am now developing a software that can communicate instantly and make video calls!"

"Video phone? Can you see people when you call?"

Zhao Guoqing nodded.

Videophones currently have three difficulties. One is the CCD chip. When I was at the 101 Institute, the Optoelectronics Research Laboratory was conducting research on 23 types of photosensitive semiconductor oxides at the same time. The high performance was not yet high, but it was usable. .

The second difficulty is image processing and compression technology. Zhao Guoqing knows the general idea of ​​​​this thing, so it should not be a big problem.

The third difficulty is also the most important one. The current 486 microcomputer cannot handle a large amount of sound and video multimedia data. Zhao Guoqing’s solution is to design a high-performance computer based on the ISA bus through the OpenGL software interface. Computing card (graphics card), assists 486 work.

At that time, you can make video calls through the 486 computer.

"Okay, I'll do whatever you say?"

Zhao Guoqing said: "Du Ting, you won't pretend not to remember what I'm here to do this time, right?"

"..."
