Rotating screen dual reflector antenna

摘要

A system for steering a beam includes a main reflector (36) that receives a signal from a subreflector (24) and reflects the signal in a reflection direction. A prism (32) refracts the signal in a refraction direction. One or more motors adjust a relative orientation between the main reflector and the prism to change a relative orientation between the reflection direction and the refraction direction to steer a beam resulting from the signal.
