Abstract:
1. A reflector assembly implementable in a scanning antenna assembly, the scanning antenna assembly having a stationary surface, the reflector assembly comprising: a support assembly fixedly attached to the stationary surface; a substantially planar first reflector panel coupled to the support assembly so as to enable rotation of the first reflector panel about a central axis of the first reflector panel; an actuator assembly comprising a single translating arm coupled to the first reflector panel and at least one motor attached to the single translating arm, wherein translational motion of the arm relative to the stationary surface caused by the at least one motor is operable to rotate the first reflector panel about the central axis back and forth through a predetermined angular range at a predetermined frequency, wherein the single translating arm passes through the stationary surface with the at least one motor being connected to the single translating arm on an opposite side of the stationary surface from the substantially planar reflector panel; and a controller coupled to the actuator assembly and configured to control at least one of the angular position and the rotation frequency of the first reflector panel, wherein the first reflector panel is configured to receive a radar-transceiver feedhorn.
