Channel correction method for instantaneous broadband receiving phased array system

The invention discloses a channel correction method for an instantaneous broadband receiving phased array system, and the method comprises the steps: placing a transmitting probe in front of a unit antenna port of a to-be-detected phased array system, and keeping the transmitting probe to directly face the normal direction of a first to-be-detected channel unit antenna; a vector network analyzer is connected with the transmitting probe and the combined output end of the phased array system to be detected; opening a to-be-tested receiving channel, turning off other receiving channels, and collecting amplitude and phase data of a receiving link of the channel; moving the transmitting probe to a next to-be-detected channel unit antenna, and sequentially collecting amplitude and phase information of other channel receiving links; and processing the acquired amplitude and phase information of all channels to obtain an amplitude correction value and a delay correction value. According to the method, the amplitude a
