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.
