Although they met again, both sides felt a little surprised.

But they just nodded to each other, and there was still no communication between the two parties, so they each went about their own business!

By the time Zhou Yang and Fan Debiao came back from the hotel, it was already half past seven in the evening.

After eating and drinking, Fan Debiao simply washed his feet and went to bed, while Zhou Yang continued to work hard on translating the manuscript.

In the dead of night, Zhou Yang finally finished translating the design parameters of this part of the radar signal receiver.

Looking at the translated manuscript, Zhou Yang couldn't help but sigh.

Although the above information only gave him part of the information, Zhou Yang still recognized it with his rich experience and technical accumulation. This was a beautiful domestically produced single-pulse airborne radar.

Airborne radar, as the name implies, is a radar installed on an aircraft. It is mainly used to control and guide weapons, implement airborne warning and reconnaissance, and ensure accurate navigation and flight safety.

The basic principles and composition of airborne radar are basically the same as other military radars, but they are more sophisticated and precise. They generally have antenna platform stabilization systems or data stabilization devices, and have the characteristics of small size, light weight, and good shock-proof performance.

All in all, the technology content is higher.

At present, airborne radar has always been a technical shortcoming in China. Compared with land-based radar, the gap with Western countries is even greater.

Therefore, Zhou Yang was not surprised at all to see foreign airborne radars in these materials!

After seeing the design parameters of this single-pulse airborne radar, Zhou Yang fell silent.

This technology is so old that even if it is translated or even imitated, it will not be of much significance to domestic fighter aircraft.

This radar from Meiliguo was developed based on the widespread application of semiconductor devices from the mid-1950s to the 1960s, and adopted technologies such as single pulse tracking, synthetic aperture, pulse compression and frequency agility.

This radar is characterized by a certain anti-interference ability, and the range, resolution and measurement accuracy have been significantly improved, and the scope of application has also been expanded. In addition to controlling aircraft guns and bomb targeting, it is also used for air-to-air and air-to-ground guidance.

missile.

Overall not bad!

But the problem is, after all, this is an old technology from more than ten years ago, and people are now installing new multi-functional pulse Doppler radars!

That’s right, it’s not research and development, it’s not design, it’s installation!

Since the 1970s, due to the development of microelectronics technology, large-scale integrated circuits, digital electronic computers, and microprocessors in airborne radars, the information processing and adaptive capabilities of radars have been improved, and multi-functional and multi-target radars have emerged.

.

Countries such as the United States and the United Kingdom have begun to upgrade their airborne radars and have successively developed a number of new radars with advanced performance, namely multifunctional pulse Doppler radars.

For example, the an/awg-9 and an/apg-66 developed by the United States, the British "Fox Hunter", and the Swedish ps-46/a are all radars of this type.

Compared with monopulse radar, airborne pulse Doppler radar not only greatly improves the radar's ability to suppress ground (water) surface clutter, but also enables combat aircraft to have the function of looking down and shooting down, expanding the combat airspace, and greatly improving

improve the fighter's comprehensive combat capabilities.

Therefore, in Zhou Yang's view, it is meaningless to study the monopulse radar that the other party has eliminated at this time.

Not only will it be a huge waste of manpower, material and financial resources, but more importantly, it will also be a waste of time. This is the most important thing.

Money is wasted and money is wasted. More than a billion people are tightening their belts, but this little money can still be saved.

But time is not good. Once it is wasted, it is really wasted, and no amount of money can buy it back.

Thinking of this, Zhou Yang felt that he should do something.

He had always been worried that his rash intervention in this matter might arouse suspicion from above, so even though he had advanced technology that could even change the world, he did not dare to use it.

So he can only lay out his plans step by step, and then slowly show off his abilities.

But seeing that these people in the project department were still wasting time on these old foreign technologies, Zhou Yang was really worried about them.

Anyway, he has done a lot of preliminary preparations. I think the guy opposite who can sleep with half his eyes open has already reported some of his situation to the above. It should be reasonable for him to show off some special abilities at this time.

Zhou Yang's idea is to design a multi-functional pulse Doppler radar first to improve the combat effectiveness of domestic fighter planes!

As for the rest, take your time.

But there are more than a dozen types of airborne radars in his mind, which one should he use?

At the moment, Zhou Yang took the manuscript paper and went through the models of airborne radars in his mind one by one.

One line at home, one line abroad!

After careful counting, there were more than twenty models.

However, some advanced models are obviously not suitable for the current era, such as the beautiful country's apg-77 active phased array radar, the French rbe2 passive electronic scanning radar, and the J-20 airborne radar, etc.

These radar technologies are so advanced that compared to current airborne radars, they are almost a product of science fiction.

What's more, the radar industry is a systems engineering, which is closely related to electronic information and materials engineering.

Even if Zhou Yang came up with the design drawings, the domestic industrial capacity would not be able to produce them.

After some comparisons, Zhou Yang decided to design the AN/AWG-9 pulse Doppler radar first.

Of course, to be on the safe side, he couldn't take out the detailed design drawings. That would be too incredible and might be cut into pieces for study.

But he can plan out some basic ideas first, just like when the Wright brothers built the airplane. There is no need for detailed drawings, just draw the basic appearance first.

As long as the painting looks good, it will definitely attract some people's attention.

Without further ado, Zhou Yang immediately spread out the manuscript paper and began to "design" his own radar.

an/awg-9 airborne radar is a fire control radar equipped on the beautiful country's f-14a/b fighter. This radar was developed in 1968 and began to be equipped with troops in 1973.

For now, only a small number of China's most advanced fighter jets are equipped.

There should be no one in China who has seen this kind of advanced radar. If you use this radar to attract some people's attention, it won't be a big problem.

Working from one o'clock in the morning to four o'clock, Zhou Yang successfully completed the "design" of the radar's circular flat-plate slot array antenna.

It's not because of how complicated this thing is, but because Zhou Yang has to make this thing have advanced performance but also leave obvious "flaws". He has to design it like a "novice" work.

It would be difficult for Zhou Yang to do this, and he had to "collect" every point!

For a technical master, this is not only challenging, but also a painful thing.

But there is no other way. In order to prevent the superiors from seeing me as a monster, I have to do this.

On the bed, Fan Debiao, who had already woken up, turned over.

Feeling the dazzling light on the ceiling and feeling a little swollen in a certain part, I immediately opened my eyes.

Seeing Zhou Yang still writing at the desk at the small table, he couldn't help but feel a little admired.

During this period of time, Zhou Yang had to work until early in the morning almost every day in order to catch up on manuscripts.

At the beginning, in order to "keep an eye on" Zhou Yang, Fan Debiao also stayed up late with him.

After struggling for more than ten days, he gave up.

This guy has a free and easy temper. If he stays up late that night, he may have to sleep until very late the next day.

But he can't do it. He is a secret service agent and Zhou Yang's nominal bodyguard.

Zhou Yang could sleep during the day, but he couldn't, so he suffered terribly during that time.

Later, I thought that Zhou Yang usually wouldn't come into contact with other people at night, so I had better not stare at him, lest I feel sleepy the next day after taking a nap during the day.

Getting up from the bed, Fan Debiao yawned and walked to the toilet.

"Go to bed early, we have to get up early to catch the train tomorrow!"

Zhou Yang said without raising his head: "Okay!"

Fan Derbiao knew that this guy didn't listen at all, so he didn't bother to pay attention to him and continued to walk to the toilet.

But when he passed by the small table where Zhou Yang worked, he discovered that he was not translating the manuscript today, but lying there drawing pictures.

At the same time, there were several crumpled up pieces of waste paper lying on the ground!

I wanted to ask Zhou Yang what he was doing, but I saw that Zhou Yang had already stood up, then turned around and fell on the bed, pulling up the quilt and covering his head.

Seeing this posture, Fan Debiao said nothing more!

ps: Let me solemnly say that the pictures in the article are not included in the word count!

Many book friends think that inserting a picture can replace many words. That is wrong. Don’t think that Lao Cang can save many words by inserting a few pictures into the book. That is impossible.
Chapter completed!
