Chapter 114 The birth of digital array radar

Of course, Chen Nian would not be unaware of things that most people with a normal mind can deduce.

He even guessed the above idea.

Therefore, for the first time, as the actual leader of the Spark Working Group, he asked the 14th Institute to further speed up the progress. At all costs, all tests of the recorded digital array radar must be completed within the next two weeks so that it can be completed within a month.

Complete the on-board experiment within 12 days, allowing the J-22, also known as the Canglong fighter, to evolve to its complete form.

In order to cope with such high-intensity work, Chen Nian thought twice and finally decided to go to 14 institutes in person and use the most detailed knowledge in his mind to promote the progress of the project.

Because he knows that this incident is actually just another manifestation of the "certain arbitration" case in the time and space of his previous life.

Their purposes are exactly the same, and the reason why they are so far ahead of schedule is entirely because of the butterfly flapping its wings.

Now that the storm has arrived, all we have to do is face it head on.

There is no retreat, which is the path to victory.

In the office of the project commander of the 14th Institute, Chen Nian had Yi Shui'er's phone number in front of him. His work in recent days was very simple. There was only one thing:

Reply to the content on the phone.

This is a temporary knowledge transmission system that he established himself.

Each phone in front of him corresponds to a module in the development process of digital array radar. If there is any problem with any module, he will ask the person in charge present to report it to him immediately, and he will answer it on the spot and make adjustments on the spot.

As a result of this operation, the efficiency of the entire project team has almost doubled. The work that was originally expected to take three weeks to complete has entered the finishing stage in just one and a half weeks.

Today is the day when China's first digital array prototype is tested.

But Chen Nian did not go to the scene. He was still sitting in this office.

This was both his own choice and the request of the intelligence agencies.

When your identity is so sensitive, it is the best choice to avoid contact with staff who do not have sufficient confidentiality sequences as much as possible.

"The reason why your scanning speed is slow now is not a hardware problem. I have checked the T/R module before and there is no problem."

"You need to check the working condition of the signal processor first to see if there is any overheating or insufficient voltage."

"If not, it's an LVDS problem. Run the bus program, do a self-test on the LVDS, and check whether the optical module has any traces of dirt or short circuit."

"Is the problem solved? Okay, that's it. Wait, I have to take another call."

Chen Nian hung up the phone with a bang, and then picked up another ringing phone.

"What? There is a problem with the timing calibration? If there is a problem with the timing calibration, first check the digital processor to see if the time and phase information is obtained accurately."

"What do you think? What are you doing? You don't know this? Just look at the antenna pattern!"

"If there is no problem with the digital processor, it is a problem with the preprocessor. Check the working status of the preprocessor."

"Have you found the problem? Just find it out and fix it quickly!"

"Hello? The far-field correction error is large? Look at the capture card! If there is no problem with the capture card, check if there is something wrong with the antenna. You need to correct the power division network now, otherwise you will not be able to get the equivalent system error."

"Take a look and see if the correction logic of the digital beamformer is correct. This is the last correction of the radial error. If there is no problem, there must be no problem."

"Is it solved? No? Is it solved?"

"That's the issue with the launch branch. Check them one by one!"

"Okay, okay, no problem"

After hanging up the phone again, Chen Nian waited quietly for two minutes. Still not waiting for a new call to come in, he finally let out a long sigh of relief.

Most of the modules that are prone to problems have experienced problems, and most of the unstable factors have been eliminated.

Next, this digital array radar should enter a stable operation stage, and what I have to do is wait for the on-site experimenters to report the final parameter data to me.

He leaned back on the chair and closed his eyes tiredly, while the white-haired old man sitting opposite him stood up carefully and asked softly with concern:

"Xiao Nian, do you want to drink some water?"

Hearing this, Chen Nian was so frightened that he sat up. He quickly supported Liu Yongtan, who was bending towards him, and said:

"Mr. Liu, stop joking with me. If I ask you to pour water, what will happen to me?"

"You sit down, I'm not tired either, let's just wait for the final results to come out."

Hearing this, Liu Yongtan hesitated for a moment and finally sat down.

He looked at the young man in front of him with emotion, and felt mixed emotions in his heart.

In the past few days, he has actually been staying with Chen Nian in this not-so-spacious command room. His original purpose was to be a leader when Chen Nian encountered difficulties, but he did not expect that such a situation would happen.

After many days, there was absolutely nothing that required his intervention!

No, not only none, but many problems that he had no clue about were easily solved by this young man.

Make strategizing and take things lightly.

Nothing in this world seemed to be able to stump him. As long as a call came in, he would answer it immediately, and then use his amazing knowledge reserve and experience that was almost impossible for his age to easily resolve the problem.

Liu Yongtan praised Chen Nian's genius more than once in person.

——

Admittedly, he knew that doing so was not good, as it was not conducive to the cultivation of newcomers and could easily make them arrogant, but

I really can’t help it!

It's like an artist. When the most beautiful scenery in the world appears in front of you, can you hold back your breath and marvel?

It's a completely instinctive action!

What makes Liu Yongtan even more gratified is that this young man behaved extremely indifferently to his unabashed praise.

He doesn't seem to care at all about other people's evaluations, no matter who this "other person" is or what his identity is.

He will only focus on doing his own thing, and his eyes will never move away from his target.

With such qualities, it’s no wonder that at such an age, he can produce so many major achievements that can turn the world upside down.

Liu Yongtan sighed heavily.

This sigh is not because of loss, but because of relief.

There is a successor!

If this trend continues, and with Chen Nian's knowledge base, the promise he made in the Spark Working Group that "he will fix the anti-stealth radar" will definitely not be an empty talk!

Even this promise may bring even greater surprises.

Thinking of this, he stood up from the chair again, ignored Chen Nian's obstruction, walked to the water dispenser and poured half a cup of water, then placed the still steaming water in front of Chen Nian, patted his shoulder and said:

"I have worked hard these past few days. When the test is completed, I will go back and have a good rest."

"Don't worry, Mr. Liu, I know it myself."

Chen Nian rubbed his eyes and was about to say a few more words of comfort to Liu Yongtan, but at this moment, more than a dozen phones on the table all rang!

Chen Nian perked up.

He almost didn't need to think before he immediately understood what was happening.

It is absolutely impossible for all modules to have problems at the same time.

Nor is it possible that the researchers are just idle and bored.

Then there is only one answer:

Digital array radar test completed.

These calls are all good news calls.

Chen Nian immediately picked up the phone and turned on the speakerphone.

As he expected, the moment the call was connected, an extremely excited voice came from the phone's built-in speaker:

"Leadership, it's done!"

"Our digital array radar test was successful!"

"data!"

"The data is that the maximum detection distance is about 710 kilometers!"

"Instantaneous sector area, 120 degrees!"

"Output power 4000 watts!"

"The detection range for RCS targets between 2 and 5 is 600 kilometers!"

"Data. Data is great!"

“Leadership, it’s really become a success!”

The data reporting was extremely confusing.

But Chen Nian's face showed uncontrollable joy.

Because he knows that even the apy-9 radar has a maximum detection range of only 500 kilometers.

And now, the small RCS target detection range of this radar has reached 600 kilometers!

This is absolute suppression of performance!

In the field of radar, we have set the goal of surpassing our opponents nearly 10 years ahead of schedule!

With this radar, Canglong will truly "put the finishing touch"!

He subconsciously turned to Liu Yongtan, who was still standing aside, but his face was already filled with tears.
Chapter completed!
