"WebRadar Wave Polarization. As implied by the term electro-magnetic radiation, the radar waves are made up of both electric and magnetic fields. When a wave is transmitted into free space from an antenna, the orientation of the electric [E] field with respect to the plane of the earth's surface determines the polarization of the wave.

WebSerious developmental work on radar began in the 1930s, but the basic idea of radar had its origins in the classical experiments on electromagnetic radiation conducted by German physicist Heinrich Hertz during the late 1880s. Hertz set out to verify experimentally the earlier theoretical work of Scottish physicist James Clerk Maxwell. Maxwell had … WebContinuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing it to …
