Phased-array antenna near-field test system and method

The invention relates to a near-field test system for a phased-array antenna. The near-field test system comprises a rotary table; the phased-array antenna system is fixed on the rotary table and comprises a wave control machine and a phased-array antenna; the horn feed source is connected with the lost network and is aligned with the central position of the phased-array antenna; the upper computer is connected with the wave control machine and used for controlling on and off of a TR assembly channel of the phased-array antenna; the transmitting pulse generating unit is used for outputting pulse signals, the pulse signals are divided into two paths to be input into the data acquisition system and the wave control machine respectively, the wave control machine sends transmitting pulses and phase codes to the TR assembly, and electromagnetic waves transmitted by the phased-array antenna system are received by the horn feed source. And the data is input to a data acquisition system through a lost network. The ph
