Most of today's radar detectors detect signals across a variety of wavelength bands: usually X, K, and K a. In Europe the K u band is common as well. The past success of radar detectors was based on the fact that radio-wave beams can not be narrow-enough, so the detector usually senses stray and scattered radiation, giving the driver time to ...
Hedy Lamarr (/ ˈ h ɛ d i /; born Hedwig Eva Maria Kiesler; November 9, 1914 [a] – January 19, 2000) was an Austrian-born American actress and inventor.

Serrate was a World War II Allied radar detection and homing device that was used by night fighters to track Luftwaffe night fighters equipped with the earlier UHF-band BC and C-1 versions of the Lichtenstein radar. It allowed Royal Air Force (RAF) night fighters to attack their German counterparts, disrupting their attempts to attack RAF bombers.

Based on this, Page, Taylor, and Young are usually credited with building and demonstrating the world's first pulsed radar. An important subsequent development by Page was the duplexer , a device that allowed the transmitter and receiver to use the same antenna without overwhelming or destroying the sensitive receiver circuitry.
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
