  Radar - Wikipedia, the free encyclopedia
Early radars used very long wavelengths that were larger than the targets and received a vague signal, whereas some modern systems use shorter wavelengths (a few centimetres or shorter) that can image objects as small as a loaf of bread or smaller.
In the transmitted radar signal, the electric field is perpendicular to the direction of propagation, and this direction of the electric field is the Polarization of the wave.
Radar jamming refers to RF signals originating from sources outside the radar, transmitting in the radar's frequency and thereby masking targets of interest.
