Chapter 606: Radar Imitation Cannot Stop
This kind of thing has a high level of confidentiality and high technology, but it is relatively easy to leak, so it is better to leave it here with peace of mind.
Regarding the leader's request for a name, Gao Zhendong smiled and said: "The name... DYC-61, a single-cycle-hardware-multiplier."
The leader looked at him: "You are too casual, you are really wasting your resources."
Gao Zhendong explained with a smile: "This thing is inherently excessive, so it would be nice to have a name."
Everyone laughed. It seemed that this thing was really unpopular in the eyes of Chief Engineer Gao. But it doesn’t matter if you don’t want to see her, we are very precious.
The next thing has nothing to do with Gao Zhendong, but the various units are "dividing the spoils". How many pieces do you want, how many pieces do I want?
At this time, the benefits of national production are reflected. There are cost restrictions on this thing, but there are no quantity restrictions.
There is no situation where you use too much and I don't have enough, so the scene is extremely harmonious. If it were replaced with other imported equipment in short supply, these comrades would fight over it.
Looking at them, Gao Zhendong quietly said to the leader of the Defense Working Committee: "Leader, can you please ask the comrades who are engaged in fighter radar here to stay for a while? I have something to communicate with them."
Yo, are you finally going to attack the fighter radar? Recalling the last time we discussed the air force system, Gao Zhendong's many ideas about radar made the leader very happy. This is easy to handle. You can keep whoever you want and stay as long as you want.
He turned to his correspondent and said a few words.
After everyone determined the quantity to the National Defense Working Committee and thanked Gao Zhendong one by one, the meeting was successfully completed and everyone got what they wanted.
Most of the comrades left the National Defense Working Committee, but two groups of people stayed. One group was engaged in fighter radars, and the other group, which Gao Zhendong did not expect at first, was those comrades who handled communications for the army.
However, the words cannot be said together, and they are divided into two groups.
The first person to communicate together was the comrade working on the radar.
Gao Zhendong asked very directly. He wanted to know the progress, problems and performance of current fighter radars.
The comrade who works on fighter jet radars is named Liu. In fact, there is only one radar being imitated now, the MiG-19 radar. He has also received the task of developing a radar for the G-5 combat type, but even the MiG-19 radar has not been imitated. It's stumbling, let alone updated.
Mr. Liu looked at the leader of the Defense Working Committee, and after receiving approval, he spoke: "Actually, we are imitating the MiG-19 radar now, but the situation is not optimistic."
"How specific?"
"The imitation process itself is not very optimistic, but more importantly, even if the imitation is successful, this radar will not be of much significance."
Regarding the performance of radar, Mr. Liu is still very clear about it.
"The antenna diameter is too small, the side lobe performance is poor, and the power itself is not good."
Even though the Zhan-5 combat type is ready to enter the equipment sequence as a multi-purpose fighter, as the Zhan-6 continues to be produced as an interceptor, the imitation of its RP-1 "Emerald" radar is also continuing.
Different from what Gao Zhendong knew in his previous life, in this life, due to Gao Zhendong's influence, the interception version of the MiG-19 with radar was delivered relatively timely. It can only be said to be useful but not of great use. The search range of this radar is only 16 kilometers, and breakdowns occur frequently.
As for things like looking down and shooting down, multi-target capabilities, etc., they are just overthinking, and they don’t exist at all.
Not to mention the MiG-19, there is no MiG-21 either.
Therefore, the comrades who imitate the RP-1 radar are very confused. Don't imitate it. The Zhan-6 has no radar use. Imitation can't be used. This thing is really useless.
"What about the research on G-5 radar?"
"We haven't started working on it yet. We haven't even finished copying the Zhan-6 radar. We have very little experience and can't start it."
The goal of imitation, in addition to obtaining equipment, is more importantly to gain experience for the research team.
Gao Zhendong thought for a moment and turned to the leader of the National Defense Work Committee: "My suggestion is, if possible, directly import the Z-6 radar and concentrate on the development of the Z-5 multi-purpose radar."
"This movement is a bit big, what's your reason?"
"Even if the MiG-19 radar is successfully imitated, it will fall behind immediately after it is born. There is little point in investing too much. The most important thing is that for the Attack-5, I am considering a new radar, based on the experience of Emerald. Maybe it doesn’t mean much.”
The RP-1 radar has nothing to do with later radars in terms of antenna, amplifier components, radar system, radar structure, back-end processing, etc. Its imitation experience cannot be said to be of any use, at most it can only be useful. A little goes a long way.
This product 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, which is very strange.
Moreover, the amplifier device is a magnetron, and the electromagnetic wave frequency is very inaccurate, which is of little use to Gao Zhendong's idea. The leader of the Defense Working Committee fell into deep thought and said after a while: "This matter cannot be decided here. Tell us what you think about the new radar."
Gao Zhendong also knew that this was the truth and did not dwell on this matter. Instead, he talked about his thoughts on the new radar.
“My idea is that the radar system, structure, antenna, and amplification components are all completely modified, and they are completely different from the RP-1.”
This step was so big that not to mention Mr. Liu, even the chief engineer of the National Defense Work Committee was stunned. No matter how he looked at it, he looked like he was talking nonsense.
"Comrade Zhendong, are your steps a bit big?"
Gao Zhendong shook his head: "It's not a big deal. We are already too far behind, but we still have some confidence. For example, back-end signal processing has been greatly improved now."
The leader of the National Defense Working Committee had more things to consider: "In this case, the imitation of RP-1 cannot stop, and the possibility of the new radar being unsuccessful must be taken into consideration. Liu Gong, in this way, RP-1 You continue to imitate. Although this radar is poor, the good thing is that it is relatively poor and the technical difficulty is relatively low.”
In order to ensure that the aircraft could be used for radar, even though it was clear that the RP-1 was already very behind, it still could not stop.
After speaking, he turned his head and said to Gao Zhendong: "We will organize another group of manpower to develop the G-5 multi-purpose radar. Since it is brand new, we will start working directly without waiting for the experience of RP-1."< br>
Originally, we wanted to wait for the team to mature, but Gao Zhendong's rapid pace made this rhythm meaningless. We simply started from scratch. It seems that this new radar should take a lot of time, so we might as well start it earlier.
Mr. Liu felt very sorry for the arrangement of the National Defense Working Committee. Gao Zhendong's new radar was very risky at first glance, but he could also guess that high risks meant high returns, which made it exciting to work on.
He thought for a while and made a suggestion: "Leader, chief engineer, if not, I will go back and hand over the copying work of RP-1 to the deputy chief engineer, and I will work on this new radar project. Experience is experience after all. It is somewhat useful and can provide maximum support to Chief Engineer Gao.”
Regarding his idea, Gao Zhendong really agreed with both hands and feet. 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 a good one!”
The leader pondered for a moment and nodded in agreement: "Well, that's indeed possible. This way both parties can be protected."
After all, imitation has physical objects, and Lao Maozi's radar technology is not very high. It is difficult to imitate, but not too much. It would be a waste to tie Mr. Liu to this backward thing since birth.
Mr. Liu was very happy, as he no longer had to deal with that crappy RP-1. Even if a new radar could not be developed, new technologies could still be learned.
Having had many meetings with Gao Zhendong, he knew very well that since Gao Zhendong dared to take such a big step, it meant that he knew it well.
"Those two leaders and Chief Engineer Gao, I will go back to arrange the handover and organize manpower to go to Chief Engineer Gao as soon as possible to push forward the new radar."
Seeing this result, Gao Zhendong was no longer in a hurry to communicate with him about the new radar technology. It was too late to wait until he was fully involved.
After Mr. Liu left, the people who walked into the conference room were comrades working on communications. They had the same idea.
"Mr. Gao, today your digital multiplier can not only help us improve the performance of the radio station, but also give us a lot of inspiration for our ideas, so I have a heartfelt request. I would like to ask Mr. Gao for your help."
"Comrade, you are too polite, tell me what it is."
"I would like to ask you to build us a hardware encryption device."
After that, he talked about the origin of the matter. They were also working on a digital radio station, which involved encryption issues.
They already have Gao Zhendong's 1200 baud rate modem, which can be used for data transmission. The data encryption algorithm used during the transmission process is still Gao Zhendong's.
——National Secret-1 (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 adequate.
But voice encryption makes them difficult. Time domain and frequency domain encryption can also be used, but they know that this analog encryption method is simple and reliable, but decryption is relatively simple under the current technical conditions, and it is difficult to face technical capabilities. It may not be useful against a strong enemy.
So they focused on digitizing voice and then encrypting the data.
The idea is very good. If you encrypt data, there are endless possibilities.
But the reality is a bit cruel. The first step of voice digitization gave them difficulties. Fortunately, today, thanks to the blessing of the Chief Engineer of the Defense Working Committee, the emergence of single-cycle hardware multipliers allowed them to see the dawn of voice digitization.
But even if digitization is achieved, real-time encryption will become a big problem. Voice calls are not like data communications and cannot wait for a long time.
