Radio Detection and Ranging, first known by the acronym RDF, later became known by the acronym RADAR. It was the secret weapon that many argue won World War II. It was a weapon that both the British and the Germans possessed during World War II. But it was the perfection of the technology by the British, with further design, development and production support from Canada and the United States, that helped Britain successfully defend itself from the marauding sorties of Hitler’s Luftwaffe.

Canada became strategically involved in the development of radar when the Tizard Mission brought technology to the National Research Council for further research, design and development.

Despite its wartime beginnings, though, radar has continued to shape the lives of Canadians, and indeed the world, through its many peaceful present-day applications, including civilian air traffic control, geographic mapping, and the microwave oven that likely sits in your own kitchen.
