Other AbstractThe invention relates to a multi-band radio telescope rapid feed source switching method based on a movable minor face. The method is characterized in that a six-rod adjusting mechanism and a rotation mechanism are adopted to together drive the minor face to move, rapid feed switching and precise focusing of a radio telescope are realized, signals are reflected to the minor face from a main face and are then converged to a focal point of the minor face after the reflection of the minor face, wherein the focal point of the minor face is the position of a receiver and feed sources. An antenna controls a computer to send an instruction for controlling the minor face rotation mechanism to drive a minor face electric shaft to rotate, and the focal point of the minor face is enabled to be superposed with the wave band feed source to be used. According to the antenna efficiency, the focusing condition is judged, a minor adjusting instruction is sent in an offset focus case, the minor face six-rod adjusting mechanism and the minor face rotation mechanism are controlled to together form a minor face movement adjusting mechanism, and the precise six-freedom-degree adjustment and focusing of the minor face are realized. The method has the advantages that the precision is high, the stability is good, the feed switching efficiency is substantially improved, and the method is especially important for the feed switching and focusing of short centimeter wave and event millimeter wave receivers high in matching precision.
