Hello peter and thanks for your comments this is how it goes
Physicist, Sir Robert Watson-Watt, was the mind behind the radar network on
the coast of England that detected incoming German aircraft in World War II.
He had worked on the radio detection of thunderstorms (hazardous to
aviators) during World War I. In 1935 he proposed a method for locating
aircraft by a radio-pulse technique. The radar system was invaluable to the
defense of Britain during the Battle of Britain in 1940. It operated day and
night over a range of 40 miles, giving the Royal Air Force information about
the height and bearing of German planes.
