摘要： A system for rapidly steering a directive beam in an antenna is provided herein. The system includes: an antenna configured to produce a directive beam; means for steering the beam rapidly, along small angles; and means for steering the beam slowly, along large angles. According to one embodiment, the antenna is implemented as a phased array antenna, wherein the means for steering the beam rapidly, along small angles, is implemented as a phased array control, and wherein the means for steering the beam slowly, along large angles, is a mechanical mechanism implemented using gimbals. According to another embodiment, the antenna includes a main reflector and a sub reflector, and wherein the means for steering the beam rapidly, along small angles, mechanically controls the sub reflector, and wherein the means for steering the beam slowly, along large angles, mechanically controls the main reflector.
