Before he could find the specific location of the German bomber group, Li Weijun's method was to force the army aviation and naval aviation to conduct high-intensity night training, planning to use fighter planes to intercept the German bomber group. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

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 hiding in the Sahara Desert.

The Sahara Desert is so big that it is not easy to find.

So Li Weiguo personally ordered that the secret equipment of the Wuhan Garrison Command in Greater Kyoto be dismantled, and then packed and shipped to Roberts Port and handed over to Li Yuanhong.

This secret equipment is a set of advanced radar equipment, which is the core part of the secret air defense system of the Wuhan Garrison Command in Greater Kyoto, which is used to detect bomber targets at a distance of 100 kilometers and at an altitude of 2,000 meters, and was originally a secret scientific research equipment of the Imperial Academy of Sciences, but with the hostile relations between China and Germany, Li Weiguo was also worried that the bombers in service with the German army would suddenly attack him with a decapitating air attack, so he ordered the Wuhan Garrison Command in Greater Kyoto to secretly install an air defense early warning radar system.

The RD4000 radar, also known as the Eagle Eye B radar system, is divided into four transmitting towers and four receiving towers, which are installed around Wuhan, Greater Kyoto, and then connected to a central radar station, with special radar soldiers responsible for monitoring and early warning.

The four towers, each 120 meters high, face four directions, south, south, west, and west, using a 400-horsepower wide-angle transmitting antenna, operating at 100 grams, and using an electronic magnetron with a wavelength of 15 centimeters. In addition, four 80-meter-high signal receiving towers use the most advanced electron tubes in the Chinese Empire to amplify the signals, and finally the radar station analyzes them to find the target signal.

After continuous testing and improvement by experts from the Imperial Academy of Sciences, the Hawkeye radar system can now detect F20 bombers at a distance of 100 kilometers and in an airspace at an altitude of 2,000 meters, Imperial-class battleships traveling on the sea within 80 kilometers, and Swordfish-class submarines floating on the surface within a distance of 5 kilometers.

This was the biggest military secret of the Chinese Empire, and originally Li Weiguo only asked the Imperial Academy of Sciences to conduct research, and did not intend to show it to the public. However, as Hitler played his cards in a variety of ways that did not follow common sense, the international situation changed, and Li Weiguo was not sure what kind of big killer Hitler would come up with, and when he discovered that Hitler's energy was concentrated in the field of air force, Li Weiguo realized the necessity of air defense.

A few years earlier, Li Weiguo had already ordered the modernization and modification of all surface combat ships of the Imperial Chinese Navy and the large-scale installation of air defense weapon systems to guard against the air threat from the German Empire.

The radar air defense system secretly installed in Wuhan, Greater Kyoto, was also based on a precautionary measure against the air threat from Germany.

However, limited by the industrial level of this era, only the Chinese Empire has the ability to manufacture high-quality vacuum tubes, but the performance gap with the tubes of later generations is still very huge, resulting in the development of many new equipment based on tubes has been restricted.

In the case of the Hawkeye B radar system in front of us, there are four transmitting antennas up to 120 meters, because each antenna cannot be rotated, and the maximum wide-angle transmitting antenna is only 100 degrees, so to complete the 360-degree defense, only four transmission towers can be installed, and the radar station is three stories high, and a simple amplification circuit system occupies the area of three rooms, which can be imagined how bloated and power-consuming.

It's like a computer in the fifties was two stories tall, and a computer with the same computing power was the size of the palm of your hand in the nineties.

Despite the fact that today's Eagle Eye B radar system is large and bloated and inefficient, in this era, it represents the world's most advanced technology level and is the only radar station in the world that has been put into practical use.

With Li Weiguo's order, this Hawkeye B radar system was dismantled and shipped to Roberts Port in Africa to help Li Yuanhong detect the location of the German bomber group and provide far more radar early warning capabilities.

"Your Majesty, I can't help it!"

Out of consideration for Li Weiguo's personal safety and the overall air defense security of Wuhan, Greater Kyoto, Zhang Xiaoliu did not suggest that Li Weiguo send this set of radar equipment to Africa.

"The minister suggested that a new set of radar systems be produced and handed over to the African Front, and there is no need to dismantle this radar defense system in Great Kyoto."

Li Weiguo waved his hand and said, "It's okay!" Hold on to the important first! Unless a full-scale war broke out, German bombers did not dare to fly directly to the capital to bomb. The Imperial soldiers and civilians in the Walvis Bay area were always terrified and worried about being attacked by German bombers, so they used them first. As for the question of reproduction, the relevant departments could be ordered to resell the technology to the Imperial Defense Company, and they would be able to produce it in batches. ”

Zhang Xiaoliu was still worried about the safety of the imperial capital, but Li Weiguo had made up his mind and knew that he could not be dissuaded.

"On behalf of the 150,000 soldiers and civilians in Walvis Bay, thank Your Majesty for the emperor's grace!"

The fate of the world's only Hawkeye radar system in Greater Kyoto was thus decided, and the main engine of the radar station began to be disassembled and then shipped to Roberts Port in Africa.

Of course, there is no need to dismantle the huge transmitter and receiving towers, and the steel structures are ready-made and can be purchased directly from steel companies.

This incident also made Li Weiguo pay more attention to the radar system project, because if he wanted to deal with the German bomber group, the radar reconnaissance system was the most effective solution. Other tasks, such as finding the German army's secret bomber base and training fighter planes in their ability to operate at night, are all palliatives rather than cure, and without radar detection and tracking, all air raids are floating clouds.

Some time ago, the Chinese Imperial Military was very interested in Tesla's metal detectors, especially the navy, and played coquettish with Li Weiguo, and finally succeeded in asking for the key technology in the metal detectors, and handed them over to the Naval Equipment Committee for demonstration and research.

The theoretical part of Tesla's contribution to this detection technology has been widely discussed at the Imperial Academy of Sciences, especially for experts in radar detection and sonar detection, which can be said to have benefited a lot and received a lot of useful inspiration.

The bombing incident at Monrovia reminded Li Weiguo that it was necessary to speed up the construction of air defense.

Therefore, the Imperial Academy of Sciences then received Li Weiguo's will, requesting that efforts be concentrated on improving the existing Hawkeye B radar system, and that the radar be miniaturized, high-precision, and easy to operate.

In fact, the Chinese Empire has accumulated a lot of theoretical knowledge and technology in radar, for example, in the radar system, the radio broadcasting and listening technology closely related to it is actually the question of different frequency bands and whether to measure and track targets.

With radio broadcasting and reception technology as a basis, it is very easy to develop radar systems, at least in the ABCDEF bands and frequencies is enough.

Of course, the most critical thing is the electron tube and the magnetron, without these two key parts, everything is a floating cloud.

At present, the technology of the Chinese Empire in this area is constantly being refreshed, and almost within a month, a new model of electron tube and magnetron has been developed, which has continuously improved the performance compared with the previous similar products, but the imperial government has been restricting the technology in this area from being put into the market, in order to prevent it from being acquired by the German Empire.

In fact, only the research and development of electron tubes and magnetrons were allowed, but they were not allowed to be put into production, although this decree was issued by the imperial cabinet, but it was really instructed by Li Weiguo.

The reason for this was that Li Weiguo wanted to find out the real level of scientific research in the German Empire in this area.

Facts have proved that when the Chinese Empire strictly controls the release of high-tech products in this area, the German Empire's scientific and technological catch-up in this area will come to a standstill, which makes Li Weiguo understand that Hitler did not have the technology in this area, at least not yet.

As a result, Li Weiguo had reason to suspect that some enterprises had secretly smuggled the empire's high-tech electron tubes to the German Empire, or through merchants from other third countries, so he ordered the relevant departments to start a thorough investigation of the relevant channels, and soon punished a large number of traitors.

Businessmen chase profits, and if they have a few hundred percent of the profits, they are not afraid even if they risk treason.

However, under the severe crackdown of the Department of Homeland Security, these traitors were soon punished severely. At the same time, the Imperial Congress passed stricter legal provisions to severely punish those national thieves who ate inside and outside, so that the outflow of high-tech technology from the Chinese Empire was effectively stopped.

This time, feeling the great threat posed by the bomber fleet of the German Empire to the overseas garrisons of the Chinese Empire, Li Weiguo lifted the ban on a large number of military-sensitive high-tech technologies and allowed those companies of the Empire with high loyalty and secrecy to be in charge of the operation.

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

After a month of fair and open bidding, the 10 large defense enterprises of the Chinese Empire came up with their most advanced radar design products and improved technology for the Hawkeye radar system, and finally the Royal Defense Industries Group's radar improvement design plan was the best, echoing the requirements of the Chinese Imperial military, and finally won the order.

It is not an accident that the Royal Defense Industry Group was able to finally stand out, because this military industrial enterprise is owned by the royal family, is Li Weiguo's personal company, and is now handed over to the second prince Yiwang to operate.

Inheriting his mother's business acumen, Yoshiwang was not suitable for military life, and finally changed jobs after three years of military service and began to take care of various properties of the royal family.

Li Weiguo will give lessons to his children every week, and the content and concepts taught are all ahead of their time, and although Li Weiguo only knows a general and general theory about radar, he still shocks the world by taking out a random piece of content.

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

Under their influence, the military equipment experts trained by the Royal Defense Industry Group soon came up with a world-leading radar design and met the military's requirements and standards for radar.

The X-51 radar, using state-of-the-art magnetron and amplified oscillating electronic triode technology, adjusts the wavelength band of the existing Hawkeye B radar to 500 to 600 gf, with a peak power of 50 hp.

In comparison, the peak power of the X51 radar is much lower than that of the Eagle Eye B, but in terms of performance, it does not decrease but increases. Because the radar antenna is no longer a giant antenna up to 100 meters, but an air defense radar with the ability to maneuver on a 6-wheeled off-road military truck.

Of course, if you go it alone, the X51 radar is indeed inferior to the Eagle Eye B radar, after all, for the early AB band radar, the larger and higher the antenna, the better the detection effect.

However, the advantage of the X51 radar lies precisely here, because this radar does not operate 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 Hawkeye B radar, but a complete set of X51 radars can form a link system to continuously move and adjust the direction through the vehicle, which is not comparable to the Hawkeye B system.

After the link system is formed, the radar becomes a network, which greatly improves the air detection ability and accuracy of the radar defense system, and has the ability to measure the azimuth and distance of the target through the triangulation function, which is the ability that the original radar does not have.

So the military of the Chinese Empire, based on these advantages, gave the order to the Royal Defense Industry, and at the same time proposed new radar indicators.

The X51 radar, named by the military as the Hawkeye C radar, requires the delivery of the first system within three months, and its radar network needs to be able to detect high-altitude targets within 2,000 meters at a distance of 100 kilometers, and low-flying targets at 150 to 200 meters at a distance of 40 kilometers, and provide a certain accuracy of ranging and azimuth measurement functions.

In order to meet this requirement, the Imperial Chinese military even allowed the Imperial Academy of Sciences to share the latest technology on electron tubes and magnetrons with the Royal Defence Industries Group to ensure the performance of the Hawkeye C radar when it was delivered.

Just as the manufacturing of the Hawkeye C radar was stepping up, the Hawkeye B radar equipment had arrived safely at Roberts Port after a week's airlift.

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

When the 120-meter-high giant tower was erected, the morale of the entire Roberts Harbor was greatly increased, and the soldiers' fear of the bombers finally subsided, but they did not dare to be careless, after all, no one knew whether the radar system would work.

In the same way, Li Yuanhong did not dare to be careless; although the radar system was in place, the army aviation units still practiced day and night, especially at night, and the intensity of flight training was unprecedented, and several planes would fall down every day, and some pilots would pay for it with their lives.

And the naval aviation is even more miserable, the F18 fighters that take off from eight aircraft carriers often have accidents even during the day, not to mention the take-off and landing training at night, which is even more frequent.

Because the casualties of the pilots exceeded the capacity of the naval fleet command, Li Yuanhong was put under great pressure, and in the end Li Yuanhong decided to allow the naval aviation to land at the land airfield after the aircraft carrier took off at night.

The land airport at night was brightly lit as if it was day, and the speed of the propeller aircraft was slow, far less than the jet planes of later generations were too fast and prone to danger, so the night take-off and landing training was able to continue, although the pilots were very dissatisfied, but there were no complaints, which made the Chinese Imperial Military breathe a sigh of relief, after all, if there were pilots complaining about the military's inhumane training mode, which aroused widespread attention from the Chinese Imperial Public Opinion, it would still be a very troublesome thing.
