The AN/CPS-1, also known as the Microwave Early Warning (MEW) radar, was a semi-mobile, S band, early-warning radar developed by the MIT Radiation Laboratory during World War II. It was one of the first projects attempted by the Lab and was intended to build equipment to transition from the British long-wave radar to the new microwave ...
The Air-to-surface-vessel (ASV) Mark I, using electronics similar to those of the AI sets, was the first aircraft-carried radar to enter service, in early 1940. It was quickly replaced by the improved Mark II, which included side-scanning antennas that allowed the aircraft to sweep twice the area in a single pass. The later ASV Mk.
The plan position indicator, dating from the early days of radar and still the most common type of display, provides a map of the targets surrounding the radar location. If the radar antenna on an aircraft is aimed downward, a map of the terrain is generated, and the larger the antenna, the greater the image resolution.
Chain Home radar – British land-based early warning radar used during the Battle of Britain - from TRE. Düppel – German radar countermeasure called chaff in the US or Window in Britain. Darky – British backup homing system: the pilot could be talked back to his home base by HF voice radio on 6440 kHz / 6.440 MHz [7]
Chain Home was the first early warning radar network in the world and the first military radar system to reach operational status. [2] Its effect on the war made it one of the most powerful systems of what became known as the "Wizard War". [3] [4]
Early examples were hand-built, but a contract was let to Westinghouse in October 1938 to provide production versions under the Westinghouse designation "WL-530" and the Signal Corps type number "VT-122". [16] A pair of these arrived in January 1939, and were incorporated into the first SCR-270 in time to be used in the Army's maneuvers that ...
The Opana Radar Site is a National Historic Landmark and IEEE Milestone that commemorates the first operational use of radar by the United States in wartime, during the attack on Pearl Harbor. It is located off the Kamehameha Highway just inland from the north shore of Oahu , Hawaii , south of Kawela Bay .
