Chapter 178 The oversized fly swatter carrying a pole (additional 1)

   Kuznetsov?

This name should be very common here in Lao Maozi, just like Xiaoming Xiaohong in China. Many people are called Kuznetsov. As for the guy with thick glasses and bald hair in front of him, It is the research and development personnel of the long-range radar in the S-300 system, the chief engineer Ю.А.Кузнецов!

   (Two people were found, one of them didn’t know how to translate it, and after a search on Baidu, it turned out to be a word with sweet and sour pork mixed in a bunch of letters, so I had to give up.)

"Mr. Kuznetsov, nice to meet you. My name is Qin. This is my wife Zhao. We are both good friends of Nikolai. We are going back to the Far East with Nikolai. We pass by here. Come in and have a look. , this is a small gift, not a respect."

  Qin Tao waved his hand, and Zaitsev, who was always inseparable, came over with a box in his arms.

When he saw the small black blocks on the foam inside the box, with English letters on them, Kuznetsov's face showed shock, excitement, excitement, and gratitude... With trembling hands, he Carefully picked up a piece inside.

   Sure enough, it is very important to match what they like. For these scientific and technological workers, it is more meaningful to give them technical things.

   At the Gas Turbine Design Bureau, Qin Tao sent a batch of graphics computers, and now, these small black blocks sent to Kuznetsov are integrated circuits!

   "Are these purchased from the United States?" Kuznetsov asked, still trembling in his words.

Qin Tao shook his head: "No, although the above logos are English letters, in fact, these integrated circuits are produced by ourselves, but we named them after the same type of integrated circuits in the United States. We passed these integrated circuits function to invert, and then develop an integrated circuit with the same performance.”

   Speaking of integrated circuits, that is, chips, it always arouses the emotion of countless people. The quality of domestic chips is too poor, and the gap between them and the West is too big.

In the field of civilian chips, this is indeed the case. After the Institute of Computer Science of the Chinese Academy of Sciences gave up the research and development of VLSI, the gap with the world quickly widened. In later generations, although it has been striving to catch up, the gap with the West is still considerable. big.

   But, that's just civilian use.

  In the field of civilian chips, the emphasis is on performance, so the manufacturing process is getting more and more advanced. Before Qin Tao crossed, it was already a 7-nanometer, 5-nanometer technology, which shows the strength of the West in these fields.

   So, what about the military?

  Military use and civilian use are completely different.

Although in the early days, the Americans stuffed civilian 8080 processors into their Tomcat fighter radars, and the Americans also used IBM's civilian minicomputers for their Aegis systems. It's a Motorola 68000. But, that's all for the initial stage.

  Military chips do not have such a high demand for manufacturing processes. When civilian mobile phone chips have begun to advance to 5 nanometers, military chips are still a few generations behind at 28 nanometers or even 50 nanometers. 5 nanometers are not suitable. An electromagnetic pulse can burn this advanced chip.

  Military chips cannot be used abroad. If there is a back door or something, there will be big troubles on the battlefield.

  Currently speaking, the active phased array radar technology that the 14th Institute is working on is essentially an electronic technology. Every T/R component is a microelectronic product.

  As for integrated circuits, there are also some in China. The 23 institutes located in the deep mountains have been working on related technologies and have achieved many achievements.

For example, the first PMOS-type large-scale integrated circuit (LSI) in China - 120-bit MOS shift register, successfully realized the leap from small and medium-sized integrated circuits to large-scale integrated circuits; the first 1K, 4K static memory, the first block ECL circuit S12, the first generation of operational amplifier series, the first set of color TV set circuit series; the first A/D, D/A converter, the first batch of anti-additive analog circuits, etc.

Now what Qin Tao brings is the products of the 24 Institute. Compared with the advanced military chips in the West, these chips are not worth mentioning, and they are still backward. Inferior, and even occupy some advantages.

  After all, after entering the 1980s, the country once introduced chip technology from the West and proposed the 531 plan, so Lao Maozi did not have this opportunity.

(I wrote about a CNC machine tool earlier. We started to build it in the 1990s. It was just a test prototype. It will take a long time to mature, but it can be used. The same is true for these integrated circuits. The domestic ones are definitely not as good as Imported, but we can produce it ourselves, so we can use it without worry. Of course, it will take 30 years of hard work to really catch up with the West. To increase persuasiveness, let me say one more thing, after the S-300 is imported, Our technicians disassembled and researched, and found that the technology used in Lao Maozi was backward than ours, but Lao Maozi’s integration ability is really strong, it is obviously a bunch of backward parts, after being assembled, it is still very easy to use.)

   At this time, Kuznetsov opened his mouth wide when he heard Qin Tao mention that these chips were produced by China itself: "This is impossible!"

"Mr. Kuznetsov, you are a technology worker, shouldn't you be so arbitrary? If it wasn't produced by us, how could I get these integrated circuits so easily? Some of these models have been banned from being sold to us by the West. Well, our domestic inventory is one piece less, how could we be willing to take it out and give it to you?"

  Qin Tao's words are correct.

Kuznetsov looked at the black chips, and the shock in his heart was unparalleled. After he saw all the models, he let out a long breath: "You can produce these integrated circuits yourself? "

   "Yes." Qin Tao nodded: "So, you can safely and boldly use these integrated circuits in your equipment. Of course, if necessary, our technical experts can also come to help."

  What does Qin Tao want to do?

   Of course it is joint research and development!

   It is now May of 1991, and in a few months, the Red Empire will collapse. From now on, life will be very difficult for Lao Maozi.

This time Qin Tao came here to show the integrated circuits produced by his own side, just to lay the groundwork first. Now the other party will definitely not invite his own technicians to join in the research, and even these integrated circuits may not be used, but wait until next year. In the past year, Lao Maozi will naturally think of these things, and maybe he will use them.

   (Some gossip, S-300PMU1 is jointly developed by China and Russia.)

   At least for now, Qin Tao gave these integrated circuits to Kuznetsov, and he immediately gained his favor.

   "Qin, thank you for giving us these integrated circuits. Since you are Nikolai's friend, you are also my good friend. Now, can I do something for you?"

  Everything is a matter of course, Nicholas said with a smile on the side: "The big guy you developed, take us to see."

"big guy?"

   "That's right, it's the kind of oversized fly swatter."

"good."

  Plant-shaped phased array radars all look like fly swatters, but there are big and small ones. If we say that the largest fly swatter for field air defense is definitely from their Novosibirsk Scientific Research Institute of Measuring Instruments.

   When Kuznetsov led the crowd through the front yard, into the back yard, and came to an oversized trailer, Zhao Ling's eyes widened.

After graduating from university, Zhao Ling went to engage in air defense missiles. Of course, she knew how powerful this kind of large-scale phased array radar is. There are also domestic ones, but they are fixed on a mountain as a strategic early warning radar. The new radar is mounted on the trailer.

"At present, we are still developing. The digital processing system in the later stage is a big problem. If those integrated circuits are used, it may be of great help." Kuznetsov said: "Now, I can only give You deploy this radar."

That's right, the current radar is still folded and placed on the trailer. Kuznetsov entered a machine room at the rear of the trailer and started to operate. The huge antenna array was slowly erected, and the folded parts on both sides stretched out to form a Plane, and then, a huge pole, spanning both sides of the top of the antenna array.

   "Is it a double-sided phased array?" Zhao Ling asked in surprise.

It must be a passive phased array. You can tell by looking at the phase shifter above, but it is equivalent to two phased array radars back to back, which forms a huge antenna array. Even if it does not rotate, it is theoretically impossible. Omni-directional scanning capability. However, underneath it is obviously a 360-degree rotating shaft.

   Is it necessary to use both sides?

"Yes, this arrangement can allow it to obtain stronger target refreshing capabilities. In order to have a stronger search distance, the radar will mainly focus on the 90-degree sector in front of itself." These are no secrets, Ku Znetsov answered directly.

   "This antenna is bigger than the Aegis system." Qin Tao was also very emotional: "It's just that this big pole makes people very curious."

The ordinary Aegis system is just a front, active and passive are the same, but, the top of the front, perpendicular to the surface, protrudes a large pole, carrying something on one side, which makes people who see it for the first time very excited. curious.

   This involves secrets.

   Kuznetsov said with a smile: "This is our unique arrangement, Qin, guess what?"

  Since I am asked to guess, I will not be polite. Qin Tao pretended to think for a while, and then said: "I think this device is for protection. Does it protect the waveguide leading to the transmitter and receiver in the cabin?"

This thing is the front-fed horn of Lao Maozi's unique lens projection phased array system. It is unique. Qin Tao is not very clear about the specific function. Without this big guy.

  However, for this kind of thing, you only need to say a few words.

   Sure enough, when Qin Tao said this, Kuznetsov opened his eyes wide. Unexpectedly, Qin Tao actually said the same thing!

   "Nicolas, your friend is too powerful, is he engaged in radar?"

   I have given myself so many integrated circuits, and now I can say the meaning of this front-fed speaker, which is really amazing!

  Nicolas smiled: "He is in business."

   "Yes, I like to recycle junk." Qin Tao said, pointing to another rusty container trailer not far away: "I think that junk is worth a thousand boxes of Red Star Erguotou."

   Kuznetsov looked in the direction of Qin Tao's finger, his face changed slightly.

   That thing, can you exchange for a thousand cases of wine?

  In this era, there is a serious shortage of light industrial products in Lao Maozi's market, especially grain and fine wine.

In Novosibirsk, there is not much shortage of food, because it is also considered a food production area, and there are a lot of food factories, such as Beld Bread Factory, Novosibirsk Eastern Bread Factory, Karasuk Meat Processing Factory, Novosibirsk Confectionery Factory, Novosibirsk Chocolate Factory, Novosibirsk Flour Factory, etc.

   However, because of the nationwide food shortage, there is very little wine on the market, and precious food is not suitable for wine making.

  Qin Tao is very generous. First, he gave Kuznetsov so many integrated circuits as a meeting gift. Now he is going to buy some junk. What else can Kuznetsov say?

   "Since Qin likes it so much, let's give it to Qin. As for the wine..."

   "Alcohol is a must. I will contact the country and ask them to deliver it as soon as possible. Now, let's have a drink first, how about?"

  Qin Tao took one last look at the rusty trailer. The tire underneath was also flat, and it looked like a useless rag.

Zhao Ling followed Qin Tao, but it was useless, she just watched silently, watching Qin Tao keep fooling the old man, her eyes were full of admiration, and when she started drinking, she would become Qin Tao's life secretary can make Qin Tao drink with confidence.

   Drink it, the motherland needs his stomach.

  However, Qin Tao didn't drink too much. After returning to the hotel, he bragged with Nicholas for a while before returning to Zhao Ling's room.

   "Brother Tao, what is that container, worth a thousand boxes of Erguotou?" Zhao Ling couldn't help asking.

  Qin Tao smiled: "If I'm not wrong, that thing should be 5N64K."

"What?"

   "64N6's father."

   Speaking of the S-300 system, most people will only know 64N6, this famous radar, is the multiplier of the combat power of the S-300 system. This radar, code-named Big Bird (NATO code), provides a longer-distance search capability. It can even monitor ballistic missiles.

  Rome was not built in a day, and 64N6 did not come out all at once. Before this radar appeared, there was another one, that is, the 5N64 stuffed into the container!

That guy, if unfolded, is similar to the big 64N6 now, and its function is also similar. In fact, it is a long-range radar prepared for the original S-300PT system, but the S-300PT system will soon reach its end of life. Therefore, this kind of long-range radar is useless, and it can be regarded as an early model test product.

   Last time, Qin Tao got back a set of S-300PT system. Now, if he gets back this 5N64K, it can just make up a system! Even if it is something old Maozi eliminated, after all, it is only ten years old.

  This kind of 64N6 is definitely not to get involved. Qin Tao knows that the time is not yet, but 5N64 is just a trivial matter.
