It was 75 years ago this week that the Signal Corps successfully demonstrated the application of RADAR at Fort Monmouth, NJ, with a working radio pulse-echo detector, to a group of senior-level decision makers, getting the approval and funds to formulate a definite program for the development of various types of detectors. In 1942, the Army adopted the Navy’s designation of radio detection and ranging (RADAR). RADAR was regarded as one of the most important contributing factors to the Allied victory in WWII.
The first demonstration, on the 18th and 19th of May, 1937, was witnessed by the Assistant Chief of the Air Corps and representatives of the Ordnance Department and the Corps of Engineers. The show was repreated on May 26th for the Secretary of War, the Chief of Staff, the Chief of the Air Corps, and members of the Military Affairs Committees of the U.S. Senate and House of Representatives.
