It was placed into service in late 1942, and by 1944 it had also been adapted for use on surfaced submarines. With some 1,000 sets eventually being built, the Type 13 was by far the most used air- and surface-search radar of the Imperial Navy. The Type 14 was a shipboard system designed for long-range, air-search applications.
Klein Heidelberg was the code-name give to a passive radar system devised in 1941. The system was a bi-static radar system. What was unusual was that the transmitters were British rather than German! The system worked by using the reflections from the Chain Home (British coastal radar system) rather than transmitters associated with the receivers.
After the Battle of Britain, RAF Bomber Command began night attacks against German cities. Although Bomber Command had reported good results from the raids, the Butt Report showed only one bomb in twenty landed within 5 miles (8.0 km) of the target, half the bombs fell on open country, and in some cases, the bombing was seen to fall as far as 50 kilometres (31 mi) from the target.
Side view of an AN/APS-4 radar pod without its shell. The AN/APS-4, originally known as ASH (air-surface, model H) is an early military air-to-air and air-to-surface radar used by American and British warplanes during World War II. APS-4 operated in the X band at 3 cm, compared to the 10 cm S band used by most radars of the era. This allowed ...

H2X, eventually designated as the AN/APS-15, [2] was an American ground scanning radar system used for blind bombing during World War II.It was developed at the MIT Radiation Laboratory under direction of Dr. George E. Valley Jr. [3] to replace the less accurate British H2S radar, the first ground mapping radar to be used in combat. [4]
SK was a very high frequency search set for large ships. It furnished range and bearing of surface vessels and aircraft, and it could be used for control of interception. The set had both "A" and PPI scopes, provisions for operating with remote PPIs and for IFF connections, and built-in BL and BI antenn
This is a list of World War II electronic warfare equipment and code words and tactics derived directly from the use of electronic equipment. This list includes many examples of radar, radar jammers, and radar detectors, often used by night fighters; also beam-guidance systems and radio beacons.
