Robert Watson Watt, 1892 was born in Angus, Scotland on April 3, 1992. It is a small town called Brechin. When he was at school, he got good grades. During his study in university of dundee, he won many various medals. He is a headmaster. To say that schoolmasters also appreciate each other, Watson Watt was naturally admitted by a bigger schoolmaster after graduation, and became the favorite pupil of Professor Patty, the head of the Department of Physics in university of dundee. Professor Patty is a bole. Under his command, Watson Watt chose a very fresh theme radio at that time.
In fact, radio mainly deals with electromagnetic waves, which are invisible and intangible. Mainly rely on various instruments to guess. Watson Watt first engaged in radio communication, and it seems that he didn't achieve anything. However, in 19 16, he suddenly had a brainteaser and began to switch to meteorology and engage in the research of lightning detection. Lightning and thunder in the sky are bound to release a lot of electromagnetic waves. He wants to invent a device to keep the pilot away from the lightning. In fact, the frequency of lightning was similar to that of naval long-wave communication station, and it was also the main interference of radio communication at that time. His early inventions were quite successful. He once saw lightning 2500 kilometers away, but it was easy to detect but difficult to locate. He needs to invent a large antenna that can accurately point at lightning. In the whole process, the listener is often dazzled by countless lightning, but Watson Watt has gradually become a master in this field with a little experience accumulated by lightning.
1935, 12 In February, Watson Watt proposed to the British Air Force to detect aircraft by radio. At that time, radio could only be used for communication. British air force officials expressed support and encouragement for his idea, but they didn't pay the price for it! We are very supportive of your creative genius, but please show us.
On February 26th of that year, Xueba secretly manufactured two sets of receiving devices, which were secretly installed near a BBC broadcasting tower in Davenport, England, about 9.7 kilometers away from the tower. The two receiving devices are synchronized, so the radio signals can cancel each other, but they can receive signals from other directions.
A Royal Air Force bomber was arranged in a big circle around the BBC building, and Watson Watt saw the long-awaited waveform on the cathode ray tube.
1On April 2, 935, Watson Watt obtained the patent of radio detection and positioning device, abbreviated as RADAR in English, indicating that the radar successfully accessed the Internet. The British Ministry of Defence was very interested. They lacked the means to deal with German aircraft, so they strongly supported it. Then radar stations were built all over Britain.
In the famous Battle of Britain, the British radar can accurately predict the incoming German aircraft, which played a key role in the victory of air combat.
Later, in Watson Watt's hometown, people built a statue, and an old man with glasses held a launch tower at the bottom of the bottle.
