Chapter 642 Radar Technology

What is radar? If you want to understand this problem, you must understand the working principle and role of radar, as well as the changes that radar brings to all aspects of human life.

If it were in later generations, radar would be a very familiar technology that is widely used in all areas of life.

Whether it is small cars for civilian use or various military facilities, radar has greatly changed human life style.

Nearly a hundred years ago, radar was an elusive field that was still being explored for people of this era.

1. Radar Research Center of the Royal Academy of Sciences.

Since the research on radar technology in Australasia began more than ten years ago, Arthur has placed high hopes on this technology, spending a lot of money on research every year, and finally achieved certain results.

In fact, as early as the middle of World War I, the British had the idea of ​​​​detecting aircraft flying in the sky.

But the aircraft technology was not mature at that time, let alone the radar to find the aircraft.

The research and development of radar is also inseparable from radio waves. Thanks to the efforts of many pioneers in the field of radar research, 1 relevant technology is available, but it is not mature and is too complex and difficult to use.

On this basis, Australasia conducted research again and developed Australasia's first radar system for searching for enemies, which was named R1 radar by the Radar Research Center.

The full name of radar is radio detection and ranging, which means radio detection and ranging. The abbreviation is Radar, which is the origin of the name of radar.

Arthur was undoubtedly very excited to learn that radar technology had been developed in Australasia.

You must know that radar is not unimportant in promoting the field of modern military science and technology. The three armed forces of the sea, land and air are in great need of advanced radar technology.

With radar, you can quickly find enemies dozens or even hundreds of kilometers away. This kind of plug-in, which is like turning on a see-through, has an undoubted role in war.

Whether it is an aircraft, warship or tank, as long as it can be equipped with a radar system and find the enemy first, it will already have an advantage in the war.

With the development of radar, there are also various fields of radar guidance, which is another improvement for weapons.

Because of this, Arthur rushed to the Radar Research Center of the Royal Academy of Sciences without stopping, waiting to see the actual effect of Australasia's first radar.

The head of Australasia's radar research center is Tesla, a seemingly incredible choice.

In fact, Tesla's contributions throughout his research career were definitely not limited to alternating current, but also included radio, radio transmission, ball lightning, turbines, amplified radiators, particle beam weapons, solar engines, X-ray equipment, missile science, Research on remote sensing technology, aircraft, cosmic rays, radar systems, robots, etc. can also be regarded as minor achievements.

Faced with such an all-round super researcher, Arthur also handed over radar research to Tesla without hesitation. Not only did he appoint him as the main person in charge of the Radar Research Center, but he also gave Tesla an annual More than a million Australian dollars were spent on research and no expense was spared to develop the radar system.

After arriving at the Radar Research Center, Arthur finally saw this famous figure in the history of scientific research again.

Known as the scientist closest to God, the current life trajectory is completely different from that in history.

After joining Australasia, Tesla's reputation in the scientific research community has grown. Not only did he obtain the title of baron for his alternating current and subsequent scientific research, he also served as the honorary vice-president of the Royal Australasian Academy of Sciences. In terms of identity and status, he has become one of the highest-ranking people in the entire country.

Unlike what history describes as poverty in his later years, Tesla's current net worth should be among the top in Australasia, at least ranking among the top 100.

Just relying on the funds and land awarded by Arthur, Tesla's worth has exceeded 100,000 Australian dollars.

Coupled with the annual income brought by his title and status, Tesla's total assets are at least more than 500,000 Australian dollars, which is a worth that many capitalists cannot reach.

After seeing Tesla, he stopped Tesla from saluting, and Arthur quickly asked: "How is the situation? Tesla."

Tesla replied: "Your Majesty, please see, this is our R1 radar that has been improved and added some new technologies.

Its principle is to use radio waves to hit a target or be reflected, and receive the reflected radio waves to reveal the location information of the enemy.

In order to make the radio waves reach a wider distance, we deliberately used a high-power high-frequency transmitter and increased the power of the receiver. Finally, we can reflect the enemy's position information on the cathode electron tube. "

The design concept of radar is somewhat similar to that of bats. Bats are animals that also rely on sound waves to find direction. The way to determine direction is by the propagation and reflection of sound waves.

Naturally, radar uses not sound waves, but radio waves that were recently developed.

Because most of the enemy's weapons are made of steel, these big guys are easily reflected by radio waves, which appear on the negative electrode tube to form a picture.

The negative electrode tube is what made up the previous TV. It is equivalent to a display screen used to display specific information about the enemy.

Arthur nodded and asked with satisfaction: "Can we ensure that we can effectively search for the enemy?"

The news about the development of radar is good, but what Arthur wants is an effective radar. In other words, it must be able to accurately search for enemies.

After all, there is no so-called stealth technology yet, and it is impossible for any man-made object to escape radar detection.

Under such circumstances, the efficiency and range of the radar become very important, and the accuracy of the search target is also an important factor in testing the effectiveness of the radar.

"This is what I want to report to you, Your Majesty." Tesla said excitedly: "After our experiments and tests, the range that simple radio waves can be reflected is not wide. But if pulse waves are used, It can greatly enhance the distance and signal strength that can be reflected.

Your Majesty, please see, this is the 12 cm long signal wavelength generated by the magnetron in our experiment. This means that we can detect other ships in any weather, including fog and night. This has changed the entire history of navigation. It also means that our fleet can have the ability to fight in fog and night. "

What are you most afraid of in a naval battle? It's just foggy days and dark nights. Although it is a battle between large battleships and various warships, people are still in control after all.

If the visibility is relatively low, this will greatly reduce the combat capability of the warship. Not even joking, when the visibility is extremely poor, you can't even find the enemy anywhere.

But if a warship is equipped with such a radar, not to mention accurate positioning, it can at least receive the approximate position of the enemy, which plays a vital role in a naval battle with poor visibility.

To put it bluntly, you can only attack if you know where the enemy is. You can't just attack blindly with your eyes closed!

"Have you conducted any actual experiments?" Arthur asked impatiently.

"Not yet, Your Majesty." Tesla said with some helplessness: "Large battleships are the best warships to install radar, but the navy did not agree to let me install radar."

Arthur stroked his forehead helplessly, smiled and said: "There are only a few battleships in the Navy. If you want to get one to install a radar, of course the Navy will not be willing.

Let's do this, send my order to dispatch a Monarch-class battleship, and you can install the radar at the Royal Dockyard. "

Although installing radar is also a good thing, those navies have not truly experienced the role of radar after all, so it is not surprising that they are unwilling to use the few battleships.

You must know that the number of battleships in Australasia is not large to begin with, and some of them are Monarch-class battleships built before the war. Naturally, the Navy feels even more distressed.

But I have to admit that this large radar is still more suitable for installation on large battleships.

Although it can also be installed on small frigates and coastal defense ships, it will have an impact on the overall structure of the warship, and even the changes will be quite large.

"Yes, Your Majesty!" Tesla nodded excitedly, very satisfied with Arthur's order to mobilize a battleship.

As the specific developer of radar, Tesla certainly understands the performance and specific functions of the radar it develops.

But the problem is that the big bosses in the Navy are not clear about it, which also makes Tesla, whose identity and status far exceed ordinary people, helpless.

Although you are the honorary vice-president of the Royal Academy of Sciences, not even Tesla can do anything in front of those navy.

"By the way, by the way, let the officials from the naval department come and take a look to see if radar is useful to the navy." Arthur seemed to have remembered something, and added to the guard who was about to pass the order.

Those guys in the Navy don't even need radar technology for battleships, so it's time to give it a good shake.

Of course, it is more important for the Navy to understand the importance of advanced science and technology. Although the specific size and performance of warships play a great role in naval warfare, it is not just big that is useful. Advanced technology is also very important in naval warfare.

Only by paying attention to the development of science and technology can military strength become stronger and stronger driven by technological improvements.

If you only indulge in your current achievements, decline is inevitable. No military technology can maintain its lead for decades. Nowadays, powerful technologies will eventually fall behind. If you are proud of a technology, you will not be far from falling behind and being beaten.

After giving all these instructions, Arthur looked at Tesla with a smile and said, "The opportunity is given to you. It's up to you whether you can impress those big bosses in the Navy."
