Chapter 606 Radar Imitation Cannot Stop

This kind of thing is highly confidential and requires advanced technology, but it is relatively easy to leak, so it is safer to keep it here.

In response to the leader's request for a name, Gao Zhendong smiled and said, "The name is... DYC-61, single-cycle-hardware-multiplier."

The leader looked at him and said, "You are so careless. You are really wasting resources."

Gao Zhendong explained with a smile: "This thing is originally a transition, it's good to have a name."

Everyone laughed. It seemed that Chief Engineer Gao didn't like this thing. But it doesn't matter if you don't like it. We treasure it very much.

What happened next had nothing to do with Gao Zhendong, but was a matter of "dividing the spoils" among the various units. You wanted some pieces and I took some pieces.

At this time, the benefits of domestic production are reflected. This thing has cost limits, but no quantity limits.

There is no situation where you use more and I have less, so the scene is extremely harmonious. If other imported and in-demand equipment were used, these comrades would fight over them.

Looking at them, Gao Zhendong quietly said to the leader of the Defense Work Committee: "Leader, can you ask the comrades working on the fighter radar here to stay for a while? I have something to communicate with them."

Oh, are you finally going to start with the fighter radar? Thinking back to the last time we discussed the air force system, Gao Zhendong had many ideas about radar, and the leader was very happy. This is easy to do. You can keep whoever you want and keep them for as long as you want.

He turned and said a few words to his communicator.

After everyone confirmed the quantity with the Defense Working Committee and thanked Gao Zhendong one by one, the meeting was considered a success and everyone got what they wanted.

Most of the comrades left the Defense Work Committee, but two groups stayed. One group was those who were engaged in fighter jet radar, and the other group was a group that Gao Zhendong did not expect at first. They were the comrades who were engaged in communications for the troops.

But we can't talk at the same time, we still have to split into two groups.

The first people to communicate were the comrades who were working on radar.

Gao Zhendong asked directly. He wanted to know the progress, problems and performance of the current fighter radar.

The comrade who is working on fighter radar is named Liu. In fact, the only radar he is copying now is the MiG-19 radar. He has also received the task of developing a radar for the Attack-5 fighter model. However, even the copying of the MiG-19 radar is still bumpy, let alone the updated one.

General Manager Liu looked at the leader of the Defense Work Committee, and after getting his approval, he spoke: "Actually, we are now copying the radar of the MiG-19, but the situation is not optimistic."

"What about being more specific?"

"The imitation process itself is not very optimistic, but more importantly, even if the imitation is successful, the significance of this radar is not great."

Mr. Liu is well aware of the performance of the radar.

“The antenna aperture is too small, the sidelobe performance is poor, and the power itself is not good enough.”

Even though the Gong-5 combat model was ready to enter the equipment sequence as a multi-purpose fighter, the Z-6 was still being produced as an interceptor, so the imitation of its RP-1 "Emerald" radar was also continuing.

Different from what Gao Zhendong knew in his previous life, in this life, due to the influence of Gao Zhendong, the delivery of the interceptor type of MiG-19 with radar was relatively timely. It can only be said that it was useful but not very useful. The search range of this radar was only 16 kilometers, and it malfunctioned frequently.

As for things like looking down and shooting, and multi-target capabilities, that's just wishful thinking, they don't exist at all.

Not to mention the MiG-19, there is no MiG-21 either.

Therefore, the comrades who want to copy the RP-1 radar are very conflicted. If they don't copy it, the Zhan-6 doesn't have a radar. If they copy it, this thing is really useless.

"What about the research on Gong-5 radar?"

"We haven't started yet. We haven't even finished copying the radar of the Zhan-6 yet. We have very little experience and can't get it done."

The goal of imitation, in addition to obtaining equipment, is more importantly for the research team to gain experience.

Gao Zhendong thought for a moment and turned to the leader of the Defense Working Committee: "My suggestion is that if possible, the radar of the Zhan-6 should be imported directly, and the focus should be on the development of the multi-purpose radar of the Gong-5."

"This is quite a big commotion. What's your reason?"

"Even if the MiG-19 radar is copied successfully, it is outdated from the beginning. There is no point in investing too much money in it. The most important thing is that I am considering a new radar for the Gong-5. The experience of Emerald may not be of much significance."

The RP-1 radar has nothing to do with later radars in terms of antenna, amplifier, radar system, radar structure, back-end processing, etc. The experience gained from its imitation cannot be said to be completely useless, but at most it can only be a little useful.

This thing has two antennas, one for search and one for ranging and tracking. One is on the upper lip of the air inlet and the other is in the middle of the air inlet. It's very strange.

Moreover, the amplifier is a magnetron, and the frequency of electromagnetic waves is very imprecise, which is of no use to Gao Zhendong's idea. The leader of the Defense Work Committee fell into deep thought, and after a while he said: "This matter cannot be decided here, tell me your ideas for the new radar."

Gao Zhendong also knew that this was the truth, so he did not dwell on it. Instead, he talked about his ideas about the new radar.

"My idea is to completely change the radar system, structure, antenna, and amplifier components, so that they are completely different from the RP-1."

This step was so big that not only General Manager Liu, but even the chief engineer of the Defense Work Committee was stunned. No matter how you looked at it, it seemed like nonsense.

"Comrade Zhendong, isn't this a bit too big a step?"

Gao Zhendong shook his head. "It's not good at all. We are already far behind, but we still have some confidence. For example, the back-end signal processing has been greatly improved now."

The leader of the Defense Work Committee had more to consider: "In this case, the imitation of RP-1 cannot be stopped. We must consider the possibility that the new radar will not be successful. Engineer Liu, you continue to imitate RP-1. Although this radar is inferior, it is good that it is relatively inferior and the technical difficulty is relatively low."

In order to ensure that the aircraft could use radar, even though we knew that the RP-1 was already very backward, we still couldn't stop.

After that, he turned around and said to Gao Zhendong: "We will organize another group of people to develop the Gong-5 multi-purpose radar. Since it is brand new, we will not wait for the experience of RP-1 and start working on it directly."

Originally, we wanted to wait until the team was mature, but Gao Zhendong's big steps made this pace meaningless, so we just started from scratch. It seems that this new radar will take a lot of time, so we might as well start it early.

General Manager Liu felt very sorry about the arrangement made by the Defense Working Committee. It was obvious at first glance that Gao Zhendong's new radar was very risky, but it could also be guessed that high risk meant high returns, so it would be exciting to develop it.

He thought about it and made a suggestion: "Leader, Chief Engineer, how about this? I will go back and hand over the RP-1 imitation work to the deputy chief engineer, and I will come to work on the new radar project. Experience is experience after all, it is more or less useful, and it can also support Chief Engineer Gao to the greatest extent."

Gao Zhendong really agreed with his idea. Mr. Liu is already the top fighter radar expert in the country. With his support, things should be easier to handle.

After all, although the experience is different, the theoretical knowledge he has mastered will not change.

"Leader, I think Mr. Liu's idea is great!"

The leader hesitated for a moment, then nodded and agreed: "Well, that's indeed possible. This way both sides can be protected."

After all, the imitation is a real thing, and the Russians' radar technology content is not high. It is difficult to imitate, but not too great. It would be a waste if General Liu was tied to this thing that was born backward.

Mr. Liu was very happy. Finally, he didn't have to deal with the broken RP-1 anymore. Even if he couldn't develop a new radar, he could still learn new technology.

Having attended many meetings with Gao Zhendong, he knew very well that since Gao Zhendong dared to take such a big step, it meant that he had an idea in mind.

"Then the two leaders, Chief Engineer Gao, I will go back and arrange the handover and organize the staff to find Chief Engineer Gao as soon as possible to push forward the new radar project."

Seeing this result, Gao Zhendong was no longer in a hurry to discuss the new radar technology with him. There would still be time to talk to him after he devoted himself to it.

After Mr. Liu left, the next people to enter the conference room were the comrades in charge of communications, and they had the same idea.

"Mr. Gao, today your digital multiplier not only helps us improve the performance of the radio station, but also gives us a lot of inspiration. So I have a humble request, and I would like to ask Mr. Gao for help."

"Comrade, you are too polite. Tell me what's going on."

"I would like you to make us a hardware encryption device."

After that, he explained the origin of the matter. They were also working on digital radio, which involved the issue of encryption.

They already had Gao Zhendong's 1200 baud modem, which could be used for data transmission. The data encryption algorithm used during the transmission was still Gao Zhendong's.

——GM-1 symmetric encryption algorithm.

For this, since it is non-real time and the baud rate is very low, more than 100 words per second, the speed of DJS-60D is barely enough.

However, voice encryption made them feel troubled. Time domain and frequency domain encryption can also be used, but they knew that this analog encryption method was simple and reliable, but decryption was relatively simple under existing technical conditions. It might not be useful when facing an enemy with strong technical capabilities.

So they set their sights on digitizing voice and then encrypting the data.

The idea is good, and if the data is encrypted, the possibilities are endless.

But the reality is a bit cruel. The first step of voice digitization made them feel difficult. Fortunately, thanks to the chief engineer of the Defense Working Committee, the emergence of single-cycle hardware multipliers has allowed them to see the dawn of voice digitization.

But even if digitization is achieved, how to encrypt it in real time becomes a big problem. Voice calls are not like data communications and cannot wait for a long time.
