Rebirth 1975: Tore up the call-back order at the beginning

Xipo. Institute!

After Nie Nansun and the others finished their meal, Zhou Yang invited everyone to the conference room to discuss the next joint test.

The small conference room was crowded with people.

When Mr. Nie came this time, he brought a lot of people. In addition to Professor Niu, he also brought more than 20 technical backbones, all of whom came to observe and study.

As for the No. [-] project department, Zhou Yang also called all the backbones over.

For a while, the meeting room was full of people.

Seeing that the crowd was almost here, Zhou Yang immediately said to Nie Nansun: "Mr. Nie, we've got all the people, let's start!"

Nie Nansun nodded and said: "Everyone, we are honored to gather here today to discuss the power-on test of the first pulse Doppler radar in China. This is an honor for each of us."

"However, the outside world is still skeptical about our research results. They don't think that we can develop pulse Doppler radar in such a short period of time. So this time we are not only casting swords for the country, but also Prove us. I won't say much else, it depends on your performance!"

As soon as the words fell, Zhou Yang took over the quarrel: "It is said that it is a mule or a horse. You have to take it out for a walk to find out! Now all the parts have arrived at the project department, so let's talk about the joint test. Bar!"

"Old Zheng, please tell everyone about the preparations of your test team?"

Hearing Zhou Yang's name, Zheng Aiguo was not polite. He immediately took out a document and said loudly, "After more than two months of preparation, our test team has completed the renovation of the test room and formulated a detailed joint test outline!"

"We plan to conduct a joint test on each extension first, measure the performance, and correct any problems in time. If all the extensions meet the design requirements, then conduct a joint test on the whole machine."

As soon as the words fell, Nie Nansun immediately asked: "Comrade Zheng Aiguo, what is your first step to test?"

"Put the antenna on the shelf first, and then test the search capability and the consistency of the three channels!" Zheng Aiguo said.

Hearing Zheng Aiguo's answer, Nie Nansun nodded.

He is also from a technical background, and he knows that the search capability of radar is the foundation. If the signal of the target signal source cannot be received, then the radar is worthless.

In addition, the inconsistency of the three channels is also the most common problem with new radars. It is indeed safe to test these first.

"When will the test be available?"

Zheng Aiguo immediately said: "Actually, we have already put the antenna on the shelf. As long as the monitor is in place, we can test it at any time!"

"Okay, let's assemble the extension in the afternoon and see the progress. If it is completed earlier, we will conduct a signal source search test!" Nie Nansun said.

"Yes!"

Afterwards, under the auspices of Mr. Nie, all technical backbones reconsidered the joint test outline formulated by the test team.

Except for some simple modifications to some details, there is not much change on the whole.

After the meeting, all the groups took action to install in several groups and prepare for the next extension debugging.

......

When installing in several groups, Zhou Yang and Mr. Nie came to his office!

After entering the door, Nie Nansun asked with a smile: "It's about to be tested, are you nervous?"

"Why are you nervous? It's just a test, so you won't be nervous!"

Zhou Yang said while pouring water for him.

"It seems that you are very confident in this radar. You are not nervous at all. Aren't you afraid that the antenna will not be able to receive the signal source?" Nie Nansun said with a smile.

"Hehe, I've never worried about this. If the radar we designed can't even find the signal source, then the project department should be cancelled!" Zhou Yang said confidently.

In fact, after Old Nie delivered the circular flat slot array antenna last time, Zhou Yang inspected it in detail.

Although the production of this antenna is still a little rough, and traces of manual welding can still be seen in many places, it can be seen that this antenna should have used many national treasure-level craftsmen.

It's not aesthetically pleasing, but overall it's indistinguishable from the Jaeger's industrial-produced radar dish.

Even if there is a slight difference in performance, it will not be much worse.

After the radar model is determined, a complete production line is established, and industrial production is achieved, that gap will be smoothed out.

"It's good to have confidence, and don't talk about canceling the project department. It's a miracle that you can make such achievements in such a short period of time."

Then Old Nie changed his voice and continued: "So even if the results of this test are not ideal, it doesn't matter. Whether it is me or Old Jiang, we will support you as always!"

Hearing this, Zhou Yang immediately understood that this man was here to preside over the test on the surface, but in fact he was there to suppress the situation for him.

Although he was a little moved, he knew it was unnecessary!

It's just a pulse Doppler radar, not an active phased array radar, so it's not that complicated.

"Old Nie, we'll know after testing the performance of the radar, let's talk about something else!" Zhou Yang said with a smile.

"What are you talking about?"

Zhou Yang smiled, and immediately unlocked the desk drawer, took out a stack of blueprints, and handed it to Nie Nansun.

"What happened?"

Nie Nansun asked as he took the document.

"Gunning Radar Design Drawing!"

Hearing this, Nie Nansun couldn't help shaking his hand holding the blueprint!

"You won't finish the design of the artillery reconnaissance radar within two months, will you?"

"Didn't you say that the gun sight radar is just a gadget, isn't it normal to finish the design drawing in two months?" Zhou Yang said with a smile.

Nie Nansun glared at him, but didn't say a word, and directly looked at the blueprint in his hand and the introduction of the new radar.

When he saw the parameter requirements of this radar in the file, he couldn't sit still.

He didn't even look at the blueprint, he stared at Zhou Yang and said, "Are you kidding me about this parameter, the reaction time is really 10 to 15 seconds?"

"I usually don't speak big words, and basically what I said has come true!" Zhou Yang said with a smile.

This new type of artillery reconnaissance radar was created by Zhou Yang imitating the domestic 371 radar. The performance parameters are naturally set according to 371. The measurement response time of 10 to 15 seconds is only a basic requirement.

In fact, this radar is not only fast in response time, but most importantly has a wide range of uses and high accuracy.

Functions include mortar positioning, artillery calibration, coast surveillance, search and tracking of low-altitude targets such as helicopters and small aircraft, and can also perform terrain surveys. It is an advanced all-rounder radar.

In terms of positioning accuracy, the 371 radar is enough to beat all the artillery reconnaissance radars in the world.

It can measure the ballistic trajectory through continuous positioning within 20 kilometers, and then accurately judge the position of the enemy artillery after correcting the wind deviation, with a positioning accuracy of 10 meters.

In layman's terms, as long as the opponent's artillery dares to fire, we can calculate the opponent's position through radar, and the deviation will not exceed 10 meters.

If one's own artillery counterattacks according to this positioning, it can easily destroy the opponent's artillery positions.

"You kid, are you going against the sky!"

Although Nie Nansun mainly studies early warning radar and airborne radar, he also understands the battlefield role of artillery reconnaissance radar.

He knew very well that if the performance of the artillery reconnaissance radar designed by Zhou Yang and the others was really so good, it would be equivalent to installing a pair of clairvoyance eyes for the artillery.

This kind of artillery can really be invincible on the battlefield. It can be said that such a gadget can increase the firepower output of the artillery to the extreme, greatly improving the combat capability of the artillery and the survivability of the battlefield. .

"It's not that exaggerated. Let's take a look at the drawings first. If it's okay, you can get all these parts out quickly, so we can carry out the next test work!" Zhou Yang said with a smile.

"Hahaha, with your words, I have to fix these parts for you!"

"Then I'll wait for your good news!"

"Do not worry!"

Afterwards, Nie Nansun seriously looked at the new design drawing that Zhou Yang and others had created!
