Chapter 185 TR Components

In the past, Chen Xin would definitely focus on technologies with more strategic value to China, such as aero-engine bearings, submarine towed sonar, and anechoic tiles. It doesn't work anymore. .

Because whether it is bearings, sonar, or anechoic tiles, a long test cycle is required. Even if these products are finally approved by the military, the final orders will be quite limited.

To make a simple analogy, if the military takes a fancy to the aviation bearing of the Strategic Fudge Bureau and plans to install it on the new generation of ws15 aeroengine, how many years will it take for ws15 to be put into mass production?Three to five years is not a long time.Even if it is finally put into production, the output of one or two hundred units per year is of little significance to Chen Xin. According to the current international situation, the Chinese [***] needs a large-scale replacement is not urgent.

So in Chen Xin's view, this kind of business is more like technical assistance than making money.

The same is true for towing sonar and anechoic tiles. The construction period of a nuclear submarine is three to five years. If a large-scale order from the military comes, the flowers will have withered long ago.

Therefore, compared with other parts orders, the t/r component (transmitting/receiving component) of active phased array radar is the most reliable and most suitable product for mass production.

Everyone knows that radar is an electronic device that emits electromagnetic waves through an antenna to irradiate a target and receives its echo, thereby obtaining information such as the distance, azimuth, and height of the target.

The so-called active phased array radar is composed of a large number of transmitting/receiving modules (t/r modules), and each transmitting/receiving module generates and receives radio waves by itself.

Therefore, compared with ordinary radar, the beam pointing of phased array radar is very flexible and fast. One radar can form multiple reading beams at the same time, and realize multiple functions such as search, identification, tracking, guidance, and passive detection at the same time.Phased array radar has a very powerful multi-target engagement capability, can monitor and track multiple targets at the same time, and its anti-jamming performance is far superior to ordinary radar.

Since the 60s, phased array radar has become the key research and development equipment of military powers such as Europe and the United States.In the 70s, countries such as Europe and the United States had developed a variety of phased array radars. However, due to the high cost and the immature production technology of t/r components, it was not until the 80s that phased array radars were truly equipped with troops.

Among them, the most typical representative is the an/spy-1 radar in the Aegis combat system of the US Navy.

This set of radar has four pieces in hexagonal shape, which are respectively installed in four directions of the superstructure of the ship.

Because the radar itself does not rotate, it completely uses the method of changing the beam phase to scan the airspace targets in front of the radar at a rate of several times per second.The first-generation spy-1a radar weighs up to 12000 pounds per piece, with 140 sets of modules on it, and each module contains 32 transmit/receive and phase control units.

The an/spy-1 radar began to develop in 1965, and the sea test was launched in 1974. The first system entered the US Navy in 47 with the first Ticonderoga-class cruiser, the USS Ticonderoga (cg-1983). Later developed into a destroyer, Ali?The first Arleigh of the Burke-class destroyer?USS Burke (DDG-51) entered service with the US Navy in 1991.

At present, the largest number of t/r components in the world is the x-band radar in the theater high-altitude missile defense system of the United States.

This radar consists of many small radomes and a phased array radar antenna weighing 1814 tons (4 million pounds). The phased array radar covers an area of ​​384 square meters and has more than 2 transmit-receive (t/r) modules , these transmitting and receiving modules are distributed in a large grid. This distribution method enables the radar to track extremely long-distance targets to support the guidance of targets in the outer atmosphere of the Theater High Altitude Area Missile Defense System (thaad). This array radar needs more than 100 million watts of electricity to function properly.

It can be seen that the number of t/r components in phased array radar is very considerable. It can not only complete the radio wave receiving function but also complete the transmitting task, and can also perform phase scanning on the antenna. Therefore, the t/r component is useful One of the core components of the source phased array radar, its performance, reliability and development cost will directly affect the success or failure of the phased array radar system.

At present, the development level of t/r components is the most advanced in the United States. The x-band ground-based radar in its thhad system uses as many as 25344 t/r components, and the c-band ground-based phased array radar in the artillery positioning system (cdbra) uses 2700 t/r components. There are 2 t/r components, while spaceborne l-band active phased array radars usually contain 10 to [-] t/r components, and there are as many as tens of thousands of t/r components used in strategic early warning aircraft, It can be said that the active phased array radar is built with t/r components.

For countries around the world, the practical progress of active phased arrays will mainly depend on factors such as the performance and price of t/r components. Development in the direction of broadband, solid state and integration.

Domestic research on phased array radar t/r components has also made great progress since the mid-90s. The KJ-2000 early warning aircraft and the China Aegis system on the 052c guided missile destroyer are typical representatives.However, since domestic monolithic microwave integrated circuit (mmic) technology is not very mature, basically hybrid microwave integrated circuit (hmic) is the mainstay. In terms of t/r component production, especially in terms of cost control and yield, Compared with similar foreign products, there is still a considerable gap.

Therefore, as long as Zhanhuju can provide the military with low-cost and high-quality t/r components, it will definitely be favored by the military.

Moreover, there are tens of thousands of t/r components in phased array radar, which are widely used in modern weapon systems, whether it is airborne phased array radar or shipborne phased array radar, or even the Chinese version of national missiles. The x-band radar in the defense system (cnmd) has a very large demand for t/r components. As long as Chen Xin grabs a part of the order from the military, he may be able to solve the funding problem of the science fiction film and television studio. .

These thoughts were fleeting in Chen Xin's mind, and Chen Xin hurriedly called into the room: "Steel coin, steel coin..."

Gang Bian came out of the room staggeringly with a piece of gold in his arms, and said, "Old Dou, what's the matter?"

Chen Xin said excitedly: "Gangyi, can you make the t/r components in the phased array radar?"

The steel coin flashed its electronic eyes and said, "What's so difficult about it, as long as you give me gallium metal, I can make it casually."

Chen Xin's eyes lit up, and he said, "Alright, I'll go buy some gallium metal in two days."

………………

The next day, Wu Jun took Osborn and the others directly to the Jiangcheng City Administration to pay a visit to the Mayor of Jiangcheng City, Chen Yuanliang.

He has been working in Jiangcheng for more than half a year, and has become the most watched digital film and television special effects company in China with his little Cybertron Digital. "Bring Her Eyes" and the upcoming "Country Teacher" have made Cybertron Digital famous in China. Many film companies are in the limelight for a while, and Wu Jun has also accumulated a lot of fame in Jiangcheng's business circle.

Compared with Wu Jun, Chen Xin is much more low-key in dealing with people. On weekdays, he basically entrusts Wu Jun with all the affairs related to politics. Forged a certain friendship.

But this time, when he went to Jiangcheng City Mayor Chen Yuanliang, it was Chen Xin who told Wu Jun.

The father of Chen Yuanliang and Mu Yunshan was a life-and-death comrade-in-arms. He was awarded for his meritorious service in the southern Xinjiang self-defense counterattack in the 80s.

Now that he is only [-] years old, he is already an important position as the mayor of a sub-provincial capital city, and with the strong support of Mr. Mu behind him, as long as there are no major accidents, it should not be a problem to enter the highest bureau. As for whether he can become a few One of the great elders, it depends on his fate.

Before leaving the capital last time, Mu Yunshan told Chen Xin that if the company encountered any problems in the Jiangcheng area, he could go directly to Chen Yuanliang, and Chen Xin asked Gangbi to investigate the net worth of the mayor of Jiangcheng City who had a good reputation.

In the end, Lingling finally figured it out, Chen Yuanliang had three houses in total, and the total assets of all the immediate family members in the family were less than 300 million. From the perspective of Chen Yuanliang's status, this could be regarded as a breeze in his sleeves.

Chen Xin has a good impression of the mayor. As long as the sci-fi film and television city project is completed in his hands, it may not be impossible for this project to become a step up for Chen Yuanliang in the future.

However, there was another important reason why they didn't accompany them to visit Chen Yuanliang this time, because the premiere of "Country Teacher" was about to be held in the capital, and Chen Xin needed to attend it in person.
