Did a Canadian invent radar

Answer 1

No is the short answer...... RADAR is an acronym for Radio Detection and Range Christian Hülsmeyer, a German inventor, developed a primitive detector for collision avoidance device for ships in 1904 . It was only effective over a distance of about 1 mile , but could give no indication of range , merely ringing a bell . It used the current technology of a spark gap transmitter , which creates a signal on a wide frequency band and may have been susceptible to interference from the Marconi shipping radios. In between WW1 and WW2 there was rapid progress in radio technology , patents were filed for several devices in the U.S.A. , U.K. and Germany which subsequently became part of RADAR . Thus the parts were available and research was followed in all three countries . In the U.K. Robert Watson Watt had already been purchasing crt(cathode ray tubes)from Germany , for use in displaying his lightning detectors , when his work was extended to detect echoes from aircraft . He helped to develop versions of RADAR for aircraft use against night fighters and submarines . After the war he live for a time in Canada which may have prompted the question....... Scientists at the U.S. Naval Research Laboratory in Washington, D.C., were among the first to use radar to detect aircraft in the early 1930's...but they had only one or two sets at a time when the U.K. was building a network of overlapping systems. When the U.S.A. joined WW2 there was an exchange of knowledge between the U.K. and U.S.A to produce the best mix possible to do the job . As with many high tech inventions , there were many people involved........

Answer 2

Radar was not a Canadian invention. Radar was invented by the German inventor Christian Hulsm in the early 20th century.
