Mechanically scanned parabolic reflector antenna

摘要

A wave guide scanner assembly has an antenna constructed of a parabolic dish that refelects radar signals from a transceiver and reflective plate to a target. Radar signals reflected from the target are then antenna, sent back to the reflective plate, which sends the radar signal to the transceiver. The transceiver can be positioned at the focal point of the antenna, thereby omitted the reflective plate. The radar signals are then transmitted directed to the antenna from the transceiver, and sent to the target by the antenna. Reflected radar signals are then reflected directly back to the transceiver from the antenna. The antenna oscillates back and forth.
