In general the term is applied to Doppler radars operating in the VHF–UHF band (30 MHz–3 GHz) that determine the wind by measuring the line-of-sight Doppler shift of scattered signals ( Bragg scattering) from refractive index fluctuations caused by turbulence ( see clear-air echo ).

WebRadar was installed on a German pocket battleship as early as 1936. Radar development was halted by the Germans in late 1940 because they believed the war was almost over. The United States and Britain, however, accelerated their efforts. By the time the Germans realized their mistake, it was too late to catch up.

WebDoppler Radar As mentioned above, the Doppler radar uses the Doppler effect to measure the speed at which a vehicle is moving. Named after Austrian physician Christian Doppler, the Doppler effect is the change of wavelength of a wave for an observer who is moving relative to the wave source. bimbo bakeries promotional merchandiseWebA radar gun is an equipment that is used to measure the speed of moving objects.
