Abstract
A fast switching, variably polarized lens is placed in front of a radar antenna which radiates an electromagnetic wave having any fixed polarization. The radiated electromagnetic wave is coupled to the lens and the switching elements within the lens transform the polarization of the radiated electromagnetic wave as commanded. Each transmit pulse may take on any polarization which the lens is capable of providing independent of the polarization of the previous transmit pulse. Similarly, during receive mode the lens can be set up to allow the radar system to receive a return signal of any polarization independent of the polarization of the return signal's associated transmit signal.
