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.

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.
The original radar display, the A-scope or A-display, shows only the range, not the direction, to targets. These are sometimes referred to as R-scopes for range scope . A-scopes were used on the earliest radar systems during World War II , notably the seminal Chain Home (CH) system.
This allowed the PPI display from the radar station to be sent simultaneously to command HQ by HF cable, or by a UHF radio link. Jagdschloss Michael B : A ponderous aerial array of two rows of eighteen Würzburg mirrors measuring 56 metres long x 7 metres high was used in the Würzmann experimental early-warning radar, and formed the serial ...
It was the U.S. Army's primary long-distance radar throughout World War II and was deployed around the world. It is also known as the Pearl Harbor Radar , since it was an SCR-270 set that detected the incoming raid about 45 minutes before the 7 December 1941, attack on Pearl Harbor commenced.
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.
It was the first Navy radar to use S-band frequencies [2] and the first surface-search radar to be equipped with a plan position indicator (PPI), the ancestor of virtually all modern radar displays. The radar was developed by Raytheon under the guidance of the MIT Radiation Laboratory and Naval Research Laboratory using the cutting-edge ...
This also changed the display from a B-scope displaying angle and range, to a plan position indicator (PPI) that produced a 360-degree view around the ship. PPIs made guiding the ship toward a target much easier as the location of a blip on the display was a direct measure of the angle and range relative to the direction of motion. [10]
