Radar in World War II greatly influenced many important aspects of the conflict. [1] This revolutionary new technology of radio-based detection and tracking was used by both the Allies and Axis powers in World War II , which had evolved independently in a number of nations during the mid 1930s.

A toy kaleidoscope. A kaleidoscope (/ k ə ˈ l aɪ d ə s k oʊ p /) is an optical instrument with two or more reflecting surfaces (or mirrors) tilted to each other at an angle, so that one or more (parts of) objects on one end of these mirrors are shown as a symmetrical pattern when viewed from the other end, due to repeated reflection.
In World War II and earlier submarines, it was the only means of gathering target data to accurately fire a torpedo, since sonar was not yet sufficiently advanced for this purpose (ranging with sonar required emission of an acoustic "ping" that gave away the location of the submarine) and most torpedoes were unguided.
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.
During World War II, military radar operators noticed noise in returned echoes due to weather elements like rain, snow, and sleet. Just after the war, military scientists returned to civilian life or continued in the Armed Forces and pursued their work in developing a use for those echoes.
Technology played a significant role in World War II.Some of the technologies used during the war were developed during the interwar years of the 1920s and 1930s. Many were developed in response to needs and lessons learned during the war, and others were beginning to their development as the war ended.
Work was done using a third transmitter to improve system performance. Range with a normal Freya was up to 250 km, work was underway to use a Wasserman system instead of a Freya to increase range too 350 km. (the Freya signal was too weak to trigger the Fug25a at ranges beyond 250 km), but this was not completed.
The German Radio Intelligence Operation were signals intelligence operations that were undertaken by German Axis forces in Europe during World War II.In keeping with German signals practice since 1942, the term "communication intelligence" (German: Nachrichtenaufklärung) had been used when intercept units were assigned to observe both enemy "radio and wire" communication.
