ABSTRACT:
An antenna mirror scanner for generating and directing an antenna scanner beam displaying constant polarization vectors. The antenna mirror scanner includes a non-rotating fixed-aperture antenna for transmitting and receiving an electromagnetic plane wave in a form of an antenna scanner beam and a planar reflector with a reflective planar surface. A rotational axis of the planar reflector is aligned orthogonally to a direction of propagation of the antenna scanner beam propagating towards or away from the reflective surface. A motor rotates the planar reflector to direct the antenna scanner beam incident on the reflective surface either into the non-rotating fixed-aperture antenna when the antenna mirror scanner is operating in a receive mode or from the non-rotating fixed-aperture antenna when the antenna mirror scanner is operating in the transmit mode.
