During World War II, radar technology with friend or foe identification functions such as ground radar, shipborne radar, and aviation radar had already appeared.

Of course, after World War II, radar technology has become more and more advanced, such as single-pulse angle tracking, pulse Doppler signal processing, and all the way to the 21st century infrared light, ultraviolet light, laser and other detection methods to detect enemy aircraft.

In later generations, the general aircraft detection radar was used in combination with the horizontal scanning radar and the azimuth detection radar, because in this way, the flight altitude and flight position of the enemy aircraft could be more accurately detected through the signals of the two radars.

However, in the 1940s, radar technology was not very advanced; It is more famous that in January 1936, Robert Watson Watt set up Britain's first radar station off the coast of Sofk.

Later, in order to strengthen the reconnaissance of the German aviation units, in 1937, Marconi built a total of 20 chain radar stations for the United Kingdom.

At the end of 1943, the chain-oriented radar station, the low-altitude chain-oriented radar station and the ultra-low-altitude chain-oriented radar station together formed a powerful chain-oriented radar network; And now Chen Yanlong wants to steal the British radar technology first and use it.

Moreover, he also planned to integrate the planar position PPI display with the GCI radar to develop an improved Type 7 radar that was put into use in the United Kingdom on New Year's Day in 1941, and to carry out large-scale nationwide use detection for the German Air Force.

Because the large antenna array of the Type 7 radar can rotate in the speed range of 1 to 8 revolutions per minute, it can cover 360 degrees in all directions; Compared with the manufacturing technology of the chain-oriented radar station, it is more advanced, and with the current scientific and technological strength of the German army, it can also be produced and put into use in large quantities.

Of course, he most wants to have more advanced early warning radar, air traffic control radar, and battlefield reconnaissance radar now; It is better to be able to reach the level of science and technology of the later 50-60s radar equipment.

However, if these devices were to be more advanced, there would be early warning radars as soon as 1943, and vacuum tube-magnetron radars that appeared only after 1943, and chirp pulse radars that only appeared in 47 years, and over-range early warning radar systems that existed in 50 years, could track supersonic aircraft, and then pulse Doppler radars......

However, for Chen Yanlong, a special soldier from the 21st century in his previous life, he had studied in depth the manufacturing process of some more advanced radars; So at this moment, he is absolutely 100% confident that these radar products from the 40s and 50s will be available in advance.

So when Chen Yanlong decided that he wanted to develop a more advanced jet as soon as possible, he went to his room to draw a lot of radar design drawings.

As he was drawing, he was thinking about the types of radars that he was going to deploy to Germany right away, and he was thinking about which areas of Germany to deploy them.

In the end, he still decided to make the PPI display developed by the British, the Type 7 radar integrated with the GCI radar, and the deployment of 50 radar stations, that is, the chain radar network, which is composed of chain radar stations, low-altitude chain radar stations and ultra-low altitude chain stations, all of which are built in Berlin and the suburbs of Berlin to reconnoiter the incoming British aircraft.

Moreover, after the GCI radar station is completed, he will also command the entire radar system; The development of technologies such as guidance, control and interception, as well as radar vehicles, accelerated the development of maturity.

Because he was going to be able to let the German army develop and produce advanced early warning radars, magnetron radars and chirp pulse radars before the beginning of 1944.

Even in the mid-50s, the United States was equipped with an over-range early warning radar system that could spy for supersonic aircraft, and soon after, pulse-Doppler radar.

and in 1959 the United States General Electric developed a ballistic missile early warning radar system, and space orbit surveillance radar, as well as artificial satellites.

When he was done, he stretched out and went to the floor-to-ceiling glass window of his room; Gazing at the starry night sky outside the Berlin Chancellery, I fell into deep thought.

"With less than 2 years to go until the defeat of Germany, will I really be able to change my fate?"

After that, Chen Yanlong muttered to himself with a little worry.

However, he soon put this concern to rest, and then went on to draw up the invention design of the transistor for electronic components.

The invention of the transistor, according to the historical records on the Internet in later generations, was developed in 1929, he was the engineer Lillianfeld, and also successfully applied for a patent for the transistor.

However, because of the scientific and technological level at that time and the backwardness of production technology, there was no way for this great engineer to manufacture this high-purity transistor.

In December 1947, a research team composed of Shockley, Bardeen and Bratton of Bell Labs in the United States successfully developed a point-contact germanium transistor, which led to the advent of the transistor and the opening of the prelude to the human microelectronics revolution.

In 1950, the first "PN junction transistor" was introduced.

The development of electronic components and transistors has a very important revolutionary significance and role for the rapid development of computer computers, mobile phones, radars, sonars, and various electronic devices in the future.

Therefore, if Chen Yanlong wants Germany to have the first computer and more advanced radar, sonar and other electronic equipment, then it is necessary to develop more advanced electronic components and transistors in advance and put them into various electronic devices for use.

A transistor is a semiconductor device, commonly used in amplifiers or electronic switches, and is mainly divided into two categories: bipolar transistors (BJTs) and field-effect transistors (FETs).

It is the basic building block of modern electronic circuits such as computers and mobile phones in later generations.

Of course, in addition to the need for electronic components and transistors to be developed in advance, picture tubes and integrated circuits also need to be developed in advance, in short, for the scientific and technological inventions that can improve Germany's existing electronic equipment field, Chen Yanlongdu will try his best to make it available in advance to produce more low-cost for Germany in the future, and advanced radar, electronic computers, sonar and other weapons and equipment, and apply them to the battlefield to counter the threat of Britain, the United States and the Soviet Union.

As for the design drawings and development plans of electronic component transistors, picture tubes, and integrated circuits, Chen Yanlong plans to hand them over to Holman Hauman, the "father of radar" in Germany, and the electronic component research group that will be established soon.

At a time when Chen Yanlong was in full swing trying to draw drawings and begin his deployment in the field of new electronic components as the head of the German Empire, the Japanese troops deployed in Makin Atoll were not sleepy at all, because they were now engaged in a fierce second battle of Makin Atoll with the American army.
