What is Radar? In order to understand this problem, it is necessary to understand the working principle and role of radar, as well as the changes that radar has brought to all aspects of human life.

In the future, radar is a very familiar technology that is widely used in various fields of life.

Whether it is a civilian small car or a variety of military facilities, radar has changed the way of life of human beings.

Nearly 100 years ago, radar was an unattainable and still explored field for people in this era.

19 February 1926, Radar Research Centre, Royal Academy of Sciences.

Since more than ten years ago, Arthur has placed high hopes on this technology, and he has spent a lot of money every year to research it, and finally achieved certain results.

In fact, as early as the middle of World War I, the British had the idea of wanting to detect airplanes flying in the air.

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

The development of radar is also inseparable from radio waves, and thanks to the efforts of many pioneers in the field of radar research, the relevant technology was already available in 1922, but it was not mature, and it was too complex and difficult to use.

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

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

Arthur was undoubtedly thrilled to learn that radar technology in Australasia had been born.

You must know that radar is not unimportant for the promotion of modern military science and technology, and the navy, army, and air force are in great need of advanced radar technology.

With the help of radar, you can quickly find the enemy dozens or even hundreds of kilometers away, and this kind of plug-in is like opening a perspective, and its role in the war is undoubted.

Whether it is an aircraft, a warship or a tank, as long as it can be equipped with a radar system to find the enemy one step ahead, it has already taken the lead at the level of war.

Along with the development of radar, there are various areas of radar guidance, which is another boost for weapons.

Because of this, Arthur rushed to the Radar Research Center of the Royal Academy of Sciences, waiting to see the first radar in Australasia in action.

The head of Australasia's radar research center is Tesla, a seemingly unbelievable candidate.

In fact, Tesla's contributions throughout his research career are definitely not only alternating current, but also include research on radio, radio transmission, ball lightning, turbines, amplification emitters, particle beam weapons, solar engines, X-ray equipment, missile science, remote sensing technology, aircraft, cosmic rays, radar systems, robotics, etc.

In the face of such an all-round super researcher, Arthur also handed over the research of radar to Tesla, not only appointed him as the main person in charge of the radar research center, but also gave Tesla more than one million Australian dollars a year in research expenditure, and developed a radar system at all costs.

After arriving at the radar research center, Arthur finally saw this famous figure in the history of scientific research again.

The scientist, who is said to be the closest to God, has a very different life trajectory from history.

After joining Australasia, Tesla's reputation in the scientific research community has been increasing. Not only did he earn the title of Baron for his alternating current and subsequent scientific research, but he also served as the honorary vice-president of the Royal Australasian Academy of Sciences, and he has become the highest group of people in the whole country in terms of identity and status.

It is not like the poverty in old age described in history, and now Tesla's worth should be among the top groups of people in Australasia, at least in the top 100.

With Arthur's reward for money and land alone, Tesla is worth more than $100,000.

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

After seeing Tesla, he stopped Tesla from wanting to salute, and Arthur hurriedly asked, "How is the situation?" Tesla. ”

Tesla replied, "Your Majesty, this is our improved R1 radar with some new technology.

Its principle is that the radio waves hit the target or reflect, and the reflected radio waves are received to show the enemy's position information.

In order to make the distance of the radio waves wider, we deliberately used a high-power high-frequency transmitter, and the power of the receiver was also increased, and finally the enemy's position information could be reflected on the cathode electron tube. ”

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

Naturally, the radar uses not sound waves, but radio waves, which have not been developed before.

Because most of the enemy's weapons are made of steel, these big guys are easily reflected by radio waves, and they are now on the negative electron tube.

The negative electron tube, which is what made up the previous TV, is equivalent to a display screen that is used to display specific information about the enemy.

Arthur nodded, and asked with satisfaction, "Can you ensure that the enemy is effectively searched?" ”

The news of the radar development was good, but Arthur wanted a radar that worked, in other words, he had to be able to accurately search for the enemy.

After all, there is no so-called stealth technology yet, and it is unlikely that any man-made object will escape the radar's search.

In such a situation, the efficiency and range of the radar become very important, and the accuracy of searching for targets is also an important factor in testing the effectiveness of the radar.

"That's what I want to report to you, Your Majesty." Tesla said excitedly: "After our experiments and tests, the range that can be reflected by radio waves alone is not wide. However, if a pulse wave is used, the distance and signal strength that can be reflected can be greatly enhanced.

Your Majesty, this is the wavelength of the signal generated by the magnetron in our experiment with a wavelength of up to 12 centimeters, which means that we can find other ships in any weather, including fog and night, which has changed the entire history of naval navigation, and also means that our fleet can have the ability to fight in fog and night. ”

What are you most afraid of in naval battles? It's foggy and dark. Although it is a battle between a large battleship and a variety of warships, it is still people who control it.

If visibility is low, this will greatly reduce the combat capability of the warship. Not even kidding, when visibility is so bad, you can't even find where the enemy is.

But if the warship is equipped with such a radar, it will be able to receive at least the approximate location of the enemy, not to mention accurate positioning, which will play a crucial role in a naval battle with poor visibility.

To put it bluntly, you can only attack if you know where the enemy is, and you can't just close your eyes and fight blindly!

"Did you conduct an actual experiment?" Arthur asked with some impatience.

"Not yet, Your Majesty." Tesla said helplessly: "Large-sized battleships are the best warships to install radars, but the navy did not agree to let me install radars." ”

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 radar, of course the navy will not be willing."

Now, take my orders, send a Monarch-class battleship, and you will install the radar at the Royal Shipyard. ”

Although the installation of radar is also a good thing, after all, the navy has not really experienced the role of radar, and it is not surprising that they are reluctant to come up with a few battleships.

You must know that the number of battleships in Australasia is not large, and some of them are monarch-class battleships built before the war, so the navy is naturally even more distressed.

But I also have to admit that this kind of large-sized radar is still more suitable for installation on large-sized battleships.

Although small frigates and shore defense ships can also be installed, it will affect the overall structure of the warship, and even change it is not small.

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

As the specific developer of the radar, Tesla certainly understands the performance and specific role of the radar it has developed.

But the problem is that the big guys in the navy don't know, which also makes Tesla, whose identity and status are far beyond ordinary people, helpless.

Although you are the honorary vice-president of the Royal Academy of Sciences, in front of that group of navies, even Tesla has no way.

"By the way, by the way, let those officials in the Navy Department take a look and see if the radar is useful for the Navy." Arthur seemed to remember something, and added to the guards who were going to give orders.

Those guys in the Navy don't even want radar technology for battleships, and it's time to give it a good beating.

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, they are not blindly large and useful, and advanced technology is equally important in naval warfare.

Only by attaching importance to the development of science and technology can military strength become stronger and stronger under the impetus of technological improvement.

If you only indulge in existing achievements, weakness is inevitable. No matter what kind of military science and technology can maintain a leading position for decades, and now there will be a time when powerful science and technology will fall behind.

After giving all this instructions, Arthur looked at Tesla with a smile and said, "The opportunity is for you, whether you can impress the navy and the big bosses depends on you." ”
