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

摘要

Mirror surfaces precisely ion - measuring device of a reflector antenna, wherein the mirror surfaces precision of a reflector antenna (1) is measured, the one of a plurality of mirror panels (5a) assembled main reflector (5) has,characterized bya transmitting antenna (16), which in a predetermined distance from the reflector antenna (1) is arranged;a radiation field distribution - measuring device (7) for measuring the radiation field distribution of the reflector antenna for the given distance of the transmitting antenna (16) with simultaneous control of the position of the reflector antenna (1);a mirror panel radiation field distribution - memory means (17) for storing the panel radiation field distribution of each mirror panel (5a) of the main reflector (5) as measured data;an excitation coefficient - calculating means (18) for calculating of complex excitation coefficients of each mirror panel of the main reflector according to the radiation field distribution - measuring device (7) measured radiation field distribution of the reflector antenna (1), which in the mirror plate radiation field distribution - memory means (17), which are held in the panel radiation field distribution of the mirror plate and a antennas position signal, which the position of the reflector antenna according to the control by means of the radiation field distribution - measuring device; anda mirror surfaces precision - calculating means (19) for calculating the mirror surfaces error each mirror panel and the mirror surfaces precision of the main reflector (5) in..
