Radar is derived from radio technology, but it is not just a radio that emits one reflection. It involves many things. Several radio transmitters can emit radio waves. However, it requires sufficient power and reflects it back. This requires quite powerful power. These are just the basis of radar. It is considered to have initial radar power. It can detect long-distance targets through radar. However, the distance of this target must be added to the point of that direction and distance. The latter is more important than the former to a certain extent. Without algorithms, it cannot be displayed even if it is discovered, and it cannot be accurately reflected and displayed on the radar display screen.

As a strategic weapon, the emergence of radar and land-based and sea-based directly changed the situation of the battlefield. Some of the risky drilling and interlude tactics in the past became impossible under the premise of the emergence of radar. The radar stations spread across China's borders can ensure a day-in-time early warning of ships and an hour-in-time early warning of aircraft, which ensures the safety of sea and land. However, if China wants to rise, a powerful strategic strike fleet must have, which involves more things. A radar installed on the aircraft is very critical to the aircraft carrier formation to quickly discover opponents and ensure the efficiency of reconnaissance. It is also one of the guarantees of ******* in the navy.

There is no master in China's radar research institute, which is also a very helpless thing. Chinese masters have not yet fully grown up. Before, they have been able to grow, which has given China tens of millions or even hundreds of millions of talents that can be used. Because of this kind of rape, they have not accumulated enough knowledge. Even if they have the talent of a master, they cannot grow into masters.

In the field of radio, there are masters in China. A few years ago, the radio discoverer invited back by China, was a super master in the field of electricity and radio. But Tlas is a Yugoslav. Later, he became an American citizen. Even though he was quite satisfied with China's research environment and salary, he never joined China. This is the biggest problem. Therefore, except in theory, after Yang Yuanzhao asked Taras to take action and laid the foundation for the theory of radio detection, Taras was not responsible for the rest of the work.

Before, Tras did make great contributions to the foundation of Chinese science and technology, but with the development of technology, his work has turned more to civilian use. According to the needs of civilian use of radio, such as ranging, prospecting, and alternating power generation, cutting-edge military projects like radar basically have nothing to do with him.

Tras also knew this change in China. Compared with military aspects, he prefers civilian use, such as power generation and alternating current projects, so he feels at ease. It is just about alternating current and alternating current generators. Due to patents, Tras has become a billionaire and has obtained first-class Chinese laboratories and equipment. He can freely study what he is interested in, such as bladeless propellers, long-distance power transmission, etc., which are more suitable for his appetite.

Without the premise of masters, the radar project is not very fast. Even with Yang Yuanzhao's participation, the same is true. Yang Yuanzhao is not an all-rounder, nor is he a generalist. He is just an engineer, not even a researcher. He can have his current status and is more of an all-in-one machine. In radar research, many times, he cannot get involved, and at most he can only inform the researchers of the fragmented things he hears in later generations.

Yang Yuanzhao has no knowledge of radar. Those things are all high-end things. Car radars are mostly used on civilian vehicles. Who would install this on racing cars? Almost every inch of space and quality on racing cars must be deterred. Radar, a thing that has no effect, will not be installed on racing cars. Even if it is installed, he is an engine engineer and cannot maintain that.

I vaguely remember that there was a Doppler radar in later generations. It seemed that a fighter radar was a Doppler. He proposed this point in this radar project, which made the Radar Research Institute work in which aspect? I thought it was just a name, but in Yang Yuanzhao's opinion, it should have no effect, but unexpectedly, this idea inspired these radio experts. The combination of radar and Doppler actually gave birth to new inspiration.

The researchers spent a lot of time and energy, but the effect was not without it, but it was not very large. It is expected that in a few months, the weight of the radar may be greatly reduced. From the original installation above heavy patrol to light patrol, and even destroyers can be equipped with radar. This is a great progress for sea-based weapons, but for air-based weapons, it is still useless. At present, China's destroyers are all large, and the largest destroyer has reached 2,800 tons, and even the smallest ones exceed 1,800 tons. Under such tonnage, a radar of dozens of tons is acceptable as long as the size of the radar is not too excessive. However, the aircraft has a maximum take-off weight of only about 90 tons, and there are many aerodynamic structures that cannot be done just by saying it. Most of the aircraft in later generations are in similar shapes, that is, radar and economy, with a huge radar disc, and other aircraft are just enlargement and reduction.

The radar has reached a dead end. Almost all researchers understand that they must find a new direction. Only if the direction is correct, they can produce a suitable radar. However, radar is a new product. If it were not for Yang Yuanzhao's seedlings to be used to facilitate growth, it would not appear until more than 20 years later and gradually take shape. Although there were already radars loaded on aircraft around 1940, just like the radars in World War II, they were easily disturbed and unreliable.

This is also the fundamental reason why researchers did not propose new ideas and could only modify them on the old radar, because no one could bear the responsibility for the failure of the idea. Radar is different from other research and has a very high investment. China is far beyond the world's level in semiconductors, but radar is still the result of the combination of the most advanced technologies of semiconductors and radios. Because of its advancedness, the investment is huge. Take an ordinary radar used on heavy patrol for example. The price is as high as 1.2 million, which is almost equivalent to the price of a light patrol. If it is reduced by half, the price will be at least 2 times higher. Once the construction is wrong, and problems occur during power-on and operation, the radar will not be used.

After the special project of air-based radar, the monthly cost is as high as 70 million, and it is becoming more and more intense. Even the knowledgeable researchers cannot help but be frightened. Northwestern University received a direct allocation of 1 billion yuan from the central government, and a radar research institute's distribution of projects may be 840 million yuan a year. This is still the current situation. Once a new structure is provided, more investment may be made. It is better if it succeeds, but if it fails, it will be a big trouble.

Chinese researchers are not that conservative and are not afraid to take responsibility. They are just unknown to radar and the possibility of failure is too high. If you really invest unreservedly, the monthly expenses may be 10 times that of now, and it is possible that there will be no results in a year or two.

Even Yang Yuanzhao felt a headache when he invested in this way. For the first time, he felt that it was too much to get these things out in advance. Fortunately, it was just a simple airborne radar, not a fire control system. If the fire control system and missile were added, the investment would probably be greater. He could only make suggestions according to his impression and urged the people below to conduct the experiment.

Many people know about Doppler. This is a theory proposed in the mid-to-late 19th century. It has been more than 50 years since then. It is no longer a blockade technology. This is the first time that radar has cooperated with Doppler. With Yang Yuanzhao taking over funds and promoting it, research on this aspect has continued.

Sure enough, there is similarity between the two. Based on the Doppler effect and the proposal of single pulses, some researchers have inspiration, and theory and design begin to burst out. After completing a series of theoretical and computational work, there is a 30% chance of success.

The possibility of success of 30% is already quite low in some fields. If you invest in it, you will have huge waste. However, 30% of the most cutting-edge projects in the world are no less than 30%. In the previous projects, no matter how confident and optimistic the researchers are, it is good to have a 5% success rate. With such a success rate, even if the radical researchers are, they dare not start casually, but 30%, most of the personnel see the dawn.

The original path is not clear, so you can only find another way. This unique radar has a chance of success of more than 30%, which is worth gamble. Even if it fails, it is equivalent to accumulating experience for success because the direction is right.

When everyone thought that the next prototype was to be made, unexpectedly, Yang Yuanzhao, who was working hard to promote the research on airborne radar, believed that it would be slowed down. His opinion was recognized by the chief researcher of the Radar Research Institute. He also believed that waiting, there were still some problems in previous research that had not been solved, and some were theoretical cognition problems that could not be solved for the time being, but others should be able to be solved with a little in-depth study.

The chief took out the route and direction, and everyone began to march in the direction and continued to calculate in depth. Sure enough, the results came out one by one, and some theories about the combination of Doppler and single pulses were clarified. Under the deeper theories and more personnel, five formulas about the two were calculated, and the problems that plague Doppler radar were basically solved. According to the current success rate, the success rate has exceeded 50%.

A 50% success rate, even if such a radar uses China's most advanced semiconductor materials, or even new materials that can be used only by using all-in-one machines, it is enough to try it out, and even if it fails, it can summarize the experience. (To be continued.)
