Who invented marine radar?

Answer 1

There is no "the" weather radar. Weather radars are a class of radars which can be used for gathering data on weather conditions.

refer: http://en.wikipedia.org/wiki/Weather_radar

The most commonly used weather radar at the moment is Pulse Doppler Radar. There was no 1 inventor of the PDR, so it was likely developed either by corporations or research labs. Refer to http://en.wikipedia.org/wiki/Doppler_radar#History for discussion on the origins of the more basic Doppler Radar.

Answer 2

There is some debate as to the actual inventor. The American Association of Engineers credits John Barker as the first person to use the doppler effect in speed detection in 1947. Decatur Electronics has tried to claim Bryce Brown invented it while working there in 1954, however the US Patent office has no record from them. John Barker holds patent #2629865 filed in 1946.

Answer 3

Watson-Watt was the Scottish physicist who developed the radar locating of aircraft in England. He was born in Brechin, Angus, Scotland, educated at St Andrews University in Scotland, and taught at Dundee University. In 1917, he worked at the British Meteorological Office, where he designed devices to locate thunderstorms. Watson-Watt coined the phrase "ionosphere" in 1926. He was appointed as the director of radio research at the British National Physical Laboratory in 1935, where he completed his research into aircraft locating devices. Watson-Watt's other contributions include a cathode-ray direction finder used to study atmospheric phenomena, research in electromagnetic radiation, and inventions used for flight safety.

Answer 4

Radar in general was one of those things that got invented in small steps by various individuals.

Some notable steps would be:

Chain Home...Watson Watt

Chain Home Low...Watson Watt.

Seetakt marine gunlaying radar... Hans Hollmann

H2S airborne radar...British Military.

Cavity Magnetron...Manchester (England) University.
