Before the specific location of the German bomber group could not be found, Li Weijun's method was to force the Army Aviation and Navy Aviation to conduct high-intensity training at night, and planned to use fighter jets to intercept the German bomber group.

However, Li Weiguo, who was far away in the imperial capital, had a more clever way than Li Weijun.

Of course, under Lu Haodong's reminder, Li Weiguo also speculated that the German bomber group might be hidden in the Sahara Desert.

However, the Sahara Desert is too big, and it is never easy to find it.

So Li Weiguo personally ordered the secret equipment of the Wuhan Security Command of Greater Kyoto to be dismantled, then packaged and transported to Roberts Port and handed over to Li Yuanhong.

This secret equipment is an advanced set of radar equipment. It was originally the core part of the secret air defense system of the Wuhan Security Command in Great Kyoto. It was used to detect bomber targets at a distance of 100 kilometers and altitude of 2,000 meters. It was originally a confidential scientific research equipment of the Imperial Academy of Sciences. However, with the hostility of Sino-German relations, Li Weiguo was also worried that the German bombers serving suddenly took a decapitation air strike on him, so he ordered the Wuhan Security Command in Great Kyoto to secretly install an air defense early warning radar system.

The rd4000 radar, also known as the Hawkeye Type B radar system, is divided into four transmitting towers and four receiving towers, which are installed around Wuhan, Greater Kyoto, and are then connected to the central radar station. There are special radar troops responsible for monitoring and early warning.

The four transmitting towers, each of which is as high as 120 meters, faces four directions, southeast, west and north, use a wide-angle transmitting antenna of 400 horsepower, works at 100 Gree, and use a 15 cm wavelength electronic magnetron. There are four 80 meters high signal receiving towers, which use the most advanced electronic tubes of the Chinese Empire to amplify the signal. Finally, the radar station analyzes it to find the detection target signal.

The Chinese standard is the international standard, and it is widely publicized]

After continuous testing and improvement by experts from the Imperial Academy of Sciences, the Hawkeye radar system can now be found in the airspace of 100 kilometers and 2,000 meters high, the Imperial-class battleships sailing on the sea within 80 kilometers, and the Knife-class submarines floating on the water within five kilometers.

This was the largest military secret of the Chinese Empire. Originally, Li Weiguo only asked the Imperial Academy of Sciences to conduct research, but did not intend to show it. However, as Hitler played in various ways and the international situation changed, Li Weiguo was not sure that Hitler, a lunatic, would have created a big killer. When he found that Hitler's energy was concentrated in the air force field, Li Weiguo realized the necessity of air defense.

A few years ago, Li Weiguo issued an order to modernize all surface combat ships of the Imperial Navy and install air defense weapon systems on a large scale to guard against air threats from the German Empire.

The radar air defense system secretly installed in Wuhan, Greater Kyoto is also a precautionary measure based on air threats from Germany.

However, due to the industrial level of this era, only the Chinese Empire is currently capable of manufacturing high-quality vacuum tubes, but the performance gap with the later generations of electronic tubes is still very huge, resulting in the development of many new equipment based on electronic tubes being restricted.

As for the Hawkeye B radar system in front of you, four transmitting antennas up to 120 meters are set up. Because each antenna cannot rotate, the maximum wide-angle transmitting antenna is only 100 degrees, so to complete the 360-degree defense, you can only install four transmitting towers. The radar station is three stories high, and a simple amplification circuit system occupies the area of ​​three rooms. It is conceivable how bloated and power-consuming it is.

This is like a computer in the 1950s was as high as two floors, while a computer with the same computing power was only as big as a palm in the 1990s.

Although today's Hawkeye B radar system is huge, bloated and inefficient, it represents the most advanced technology level in the world and the only radar station in the world that has been put into practical use.

With the order of Li Weiguo, this Hawkeye Type B radar system was dismantled and transported to the Port of Roberts in Africa to help Li Yuanhong detect the location of the German bomber group and provide a capability far beyond the radar warning.

"Your Majesty, you can't do it!"

In view of Li Weiguo's personal safety and the overall air defense safety in Wuhan, Greater Kyoto, Zhang Xiaoliu did not recommend that Li Weiguo transport this set of radar equipment to Africa.

"I suggest re-producing a radar system and handing it over to the African Front. There is no need to remove this radar defense system in Kyoto."

Li Weiguo waved his hand and said, "It's okay! Come first when it's important! Unless a full-scale war breaks out, German bombers will not dare to fly directly to the capital to bomb. The Imperial military and civilians in the Whale Bay area are always frightened and worried about being attacked by German bombers, so they should use it first. As for the reproduction issue, the relevant departments can be ordered to resell the technology to the Imperial Defense Company and they can mass-produce it."

Zhang Xiaoliu was still worried about the safety of the imperial capital, but Li Weiguo had decided and knew that he could not dissuade him.

"On behalf of the 150,000 soldiers and civilians in Whale Bay, I would like to thank Your Majesty for your great kindness!"

The only Hawkeye radar system in the world located in Greater Kyoto was determined by fate. The main unit of the radar station began to be dismantled and then transported to Port Roberts, Africa.

Of course, there is no need to dismantle the huge launch tower and the receiving tower. The steel structure is ready-made and can be purchased directly from the steel company.

This incident also made Li Weiguo pay more attention to radar system engineering, because if he wanted to deal with German bomber groups, radar reconnaissance system was the most effective solution. Others, such as finding German secret bomber bases and training fighter jets at night, are all curative symptoms but not root causes. Without radar detection and tracking, facing all air strikes, it is a cloud.

Some time ago, the Chinese Empire's military was very interested in Tesla's metal detectors, especially the navy. They acted coquettishly with Li Weiguo, and finally successfully asked for key technologies in the metal detectors and handed them over to the Navy Equipment Committee for argumentation and research.

Tesla contributed this detection technology, and its theoretical part was widely discussed at the Imperial Academy of Sciences, especially experts in radar detection and sonar detection, which benefited a lot and received a lot of useful inspiration.

The Monrovia bombing reminded Li Weiguo that the construction of air defense must be accelerated.

Therefore, the Imperial Academy of Sciences then received a decree from Li Weiguo, requiring the concentration of efforts to improve the existing Hawkeye B radar system, requiring the radar to be miniaturized, high-precision, and easy to operate.

In fact, the Chinese Empire has accumulated a lot of theoretical knowledge and technical accumulation in radar. For example, in radar systems, radio broadcasting and listening technologies closely related to it are actually different frequency bands and whether target measurement and tracking are carried out.

With radio broadcasting and acceptance technology as the basis, it is very easy to develop a radar system. At least it is enough to develop a radar system within a few bands of abcdef.

Of course, the most important thing is the electron tube and magnetron. Without these two key parts, everything is a cloud of romance.

At present, the Chinese Empire's technology in this area has been constantly refreshed. Almost a month later, a new model of electronic tubes and magnetrons have been developed, which has continuously improved performance compared to previous similar products. However, the imperial government has always restricted the technology in this area from being invested in the market, with the purpose of preventing it from being acquired by the German Empire.

In fact, only electronic tubes and magnetrons are allowed to be developed, but production is not allowed. Although this government order was issued by the Lord of the Empire, it was truly instructed by Li Weiguo.

The reason for doing this is that Li Weiguo wanted to understand the real scientific research level of the German Empire in this regard.

Facts have proved that when the Chinese Empire strictly controls high-tech products in this area to be put on the market, the German Empire's technological pursuit speed in this area will stagnate, which made Li Weiguo understand that Hitler did not master this area of ​​technology, at least not yet.

Therefore, Li Weiguo had reason to suspect that some companies had secretly smuggled the empire's high-tech electronic tubes to the German Empire, or smuggled them through merchants from other third countries. So he ordered the relevant departments to start thoroughly investigating relevant channels and quickly punished a large number of traitors.

Merchants pursue profits, and if they make a profit of hundreds of percent, they will be fearless even if they risk treason.

However, under the severe crackdown of the Bureau of Homeland Security, these traitors were quickly severely punished. At the same time, the Imperial Congress passed more severe legal provisions to severely punish those traitors who were scattered, effectively preventing the outflow of high-tech technology in the Chinese Empire.

This time, feeling the huge threat from the bomber group of the German Empire to the overseas garrison of the Chinese Empire, Li Weiguo lifted a large number of military-sensitive high-tech technologies, allowing companies with high loyalty and confidentiality to be responsible for their operations.

One of them is the lifting of the magnetron technology ban, which is handed over by the military to trusted defense companies to develop and produce advanced radar equipment.

After a month of fair and open bidding, ten large defense companies of the Chinese Empire successively brought out their most advanced radar design products and improved technology for Hawkeye radar systems. Finally, the Royal Defense Industry Group's radar improvement design plan was the best, and in line with the requirements of the Chinese Empire's military, they finally got the order.

It is not an accident that the Royal Defense Industry Group was able to finally stand out, because this military-industrial enterprise belongs to the royal family and is a personal company of Li Weiguo, and is now handed over to the second prince Yi Wang to run.

King Yi inherited his mother's business mind and was not suitable for military life. Finally, after serving in the military for three years, he transferred to the local area and began to manage various industries of the royal family.

Li Weiguo teaches his children every week, and the content and ideas he teaches are advanced. Although Li Weiguo only knows a general and general theory about radar knowledge, he still shocked the world if he comes up with just one content.

Of course, the children of the royal family have strict tutoring, and no one dares to tell outsiders the secrets of the royal family easily.

King Yi and his younger brothers and sisters who also don’t like to join the army jointly managed the Royal Defense Industry Group. Under their influence, the military equipment experts trained by the Royal Defense Industry Group quickly came up with the world-leading radar design and met the military’s requirements and standards for radar.

The x-51 radar uses the most advanced magnetron and amplified oscillating electronic transistor technology to adjust the band of the existing Hawkeye B radar to the 500-600 Gree band, with a peak power of 50 horsepower.

In comparison, the peak power of the x51 radar is much lower than that of the Hawkeye B, but in terms of performance, it does not decrease but rises. Because the radar antenna is no longer a giant antenna up to 100 meters, it is instead equipped with a 6-wheel off-road military truck and has maneuverable air defense radar.

Of course, if you fight alone, the x51 radar is indeed not as good as the Hawkeye B radar. After all, for early A-band radars, the larger the antenna, the higher the detection effect, the better.

However, the advantages of the x51 radar are precisely here, because this radar is not operated independently, but a radar network composed of six or eight radar systems of the same type.

Network link system, this is the biggest and most essential difference between x51 radar and Hawkeye B radar. The former represents the future development direction of radar.

An x51 radar may not be as good as an Eagle-Eye Type B radar, but a complete set of x51 radars can form a link system and continuously move and adjust the direction through on-board methods. This is not comparable to the Eagle-Eye Type B system.

After forming a link system, the radar becomes a network, greatly improving the air detection capability and accuracy of the radar defense system. It also determines the function of the triangle and has the ability to measure the target azimuth angle and distance, which is a capability that the original radar does not have.

Therefore, based on these advantages, the Chinese Empire military gave the order to the Royal Defense Industry and also proposed new radar indicators.

The military named the Eagle Eye C radar, which requires the first system to be delivered within three months. Its radar network needs to reach high-altitude targets within 2,000 meters altitude 100 kilometers away, as well as low-altitude flights of 150 to 200 meters 40 kilometers away, and provide certain accuracy ranging and azimuth measurement functions.

To meet this requirement, the Imperial Chinese military even allowed the Imperial Academy of Sciences' latest technology on electronic tubes and magnetrons to share with the Royal Defense Industry Group to ensure the performance of Hawkeye C radars during delivery.

Just as the Hawkeye Type C radar was being made, the Hawkeye Type B radar equipment was safely transported to Port Roberts after a week of air transport.

After Li Yuanhong learned that the court had given him a radar system that could provide early warning of enemy aircraft, he was happy and rushed to mobilize the best engineers in the army and quickly install the Hawkeye B radar.

When the giant tower as high as 120 meters was erected, the morale of the entire Roberts Port also increased greatly, and the soldiers' concerns about the bomber finally diminished, but they did not dare to be careless. After all, no one knew whether the radar system worked or not.

Similarly, Li Yuanhong did not dare to be careless. Although he had a radar system, the army aviation army still practiced day and night, especially the intensity of night flight training was unprecedented. Several aircraft would fall down every day, and some pilots sacrificed their lives for this.

The naval aviation corps were even worse. The F18 fighter jets that took off from eight aircraft carriers often had accidents during the day, not to mention that they took off and landed at night, and accidents occurred frequently.

Since the pilot's casualties exceeded the Navy Fleet Command's ability to withstand great pressure, Li Yuanhong finally decided to allow the Navy aviation to land at the land airport after the aircraft carrier takes off at night.
