http://www.scienceclarified.com/Qu-Ro/Radar.html WebRadar can also collect signals in different polarizations, by controlling the analyzed polarization in both the transmit and receive paths. Polarization refers to the orientation of the plane in which the transmitted electromagnetic wave oscillates. While the orientation can occur at any angle, SAR sensors typically transmit linearly polarized.
