Secrets of Radar Museum The Secrets of Radar Museum is a small museum located near Parkwood Hospital in London , Ontario , Canada . Opened to the public in 2003 , the museum was created to tell the story of the more than 6 , 000 Canadian World War II veterans who were recruited into a top - secret project during World War II involving radar . Drawn from every walk of life , and sent around the world , these veterans were held to an Oath of Secrecy that was not fully lifted until 1991 . The museum is an incorporated not - for - profit museum located in London , Ontario . It is committed to sharing Canadian radar history , from its earliest experimentation to recent advances , and most importantly , to the preservation of real life stories and personal experiences of the people who have worked and continue to work in radar , both military and civilian . Mandate . The Museum ' s mandate is threefold : About the Museum . During World War II , at the request of the British government , almost 6 , 000 Canadians were trained on RADAR and sent into every theatre of war . Sworn to an oath of secrecy that was not fully lifted until 1991 , it was only recently that these men and women were able to share their experiences . Canadian radar personnel were a crucial part of the war effort . Many of these early radar veterans went on to have leadership roles in the development of radar during the Cold War and in the Canadian electronics industry . The contributions of the thousands of men and women working on Canadian radar since 1940 , both military and civilian , have helped to protect our soldiers on the front lines , our people at home , and helped to create a technological legacy that continues to be part of our everyday lives . Collection . The Museum ' s collection includes several thousand photographs , as well as original radar equipment . While most World War II - era radar equipment has long since been destroyed , the Museum has examples of GEE , Fishpond , IFF ( Identify Friend or Foe ) radars , along with magnetron s , vacuum tubes ( known as " valves " in England ) and several hundred personal artifacts of various types .
