Mirror surfaces precisely ion - measuring device and the mirror surfaces control system of a reflector antenna

摘要

Radiation field distributions of all a main reflector (1), which forms the mirror plates (5a) are measured and stored in advance, radiation field distributions of a reflector antenna (1), which has the main reflector (5) are measured by sending a radio wave of a collimation antenna (16), which in a predetermined distance from the reflector antenna (1) is arranged is to be of the reflector antenna with simultaneous change in a position of the reflector antenna, complex excitation coefficients of each mirror panel from the radiation field distributions of the mirror plates in the radiation field distributions of the reflector antenna and the layers of the reflector antenna are calculated and the mirror surfaces precision of the main reflector is made of the complex excitation coefficients of the mirror panels calculated.
