Search Device used in Radar

Transcript
Radar has a search device that sends out a burst of radio energy that scatters out, and a little bit comes back. And they measure the time between sending out electronically and back. And radio waves travel at a constant speed. You can measure down to yards, how far that is. Navigation systems, what they did, one beacon over here, and another beacon over here … they would transmit simultaneously. And if you measure, if you’re out here, it’ll be a certain distance between receiving the two of them. Or out here, and you then have a track. And as you measure the time differences, you create a map over your existing area. So there are the two differences. One is measuring a return signal, and the other is measuring the difference in two transmitted signals. That’s the navigation side. The other is the detection side. And all other stuff bends from there.
Description

Mr. Linden explains measuring signals that are sent out.

Robert Linden

Mr. Linden was born on March 14, 1921, in Winnipeg, Manitoba. As a young boy, he always had a great fascination for air planes, which led him to seek employment in that field. When the Second World War broke out, Mr. Linden decided to join the Air Force. In 1941, he enlisted in Winnipeg as a radar mechanic, and trained in radio physics at the University of Toronto. He was later posted overseas for service with the Royal Air Force under the 537 (Night-fighter) Squadron. In 1943, he received a commission and held RCAF Officer rank, later reaching the rank of Flight Lieutenant at 236 Wing RAF. In August, 1945, Mr. Linden married in England, and returned to Vancouver to study engineering at the University of British Columbia and later his M.Sc. at MIT. In 1956, he resigned his commission and began a long career working with the federal government in Ottawa. He retired in 1978, but continued to studied history for MA at Carleton University. Mr. Linden’s keen desire to recognize the importance of radar during the Second World War led him and many other radar personnel to form the Canadian Radar History Project in 1987. This project was exhibited at Canada's War Museum in Ottawa.
