Wave beam synthesis measuring method and device of array antenna

Abstract

The invention provides a wave beam synthesis measuring method of an array antenna. The method comprises that the phase, amplitude and related distance values, including first and second distance values, of each antenna unit are obtained, the first distance value represents distance between the antenna unit and the center of a rotary table, and the second distance value represents distance betweenthe antenna unit and the adjacent antenna unit; a phase pattern of each antenna unit is calculated, and is compensated according to the corresponding phase and first distance value, and a phase errorvalue of the antenna unit is obtained; and RF signals of the antenna units are combined according to the phase, amplitude, second distance value and phase error value of each antenna unit so as to obtain the antenna wave beam. Thus, wave beam synthesis is carried out on far field test data of the single antenna, and the directional diagram equivalent test with an emitter is realized.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a beam forming method and device for measuring array antennas. Background technique [0002] In the current technology, for the electrical performance test of the array antenna or the combination of the array antenna and the radome, it is usually to simulate the actual working state, and the transmitter will be tested, but for the condition that the transmitter is not available, the array antenna and The performance of the radome is unknown.
