Random radiation radar high-resolution imaging method based on inter-pulse frequency hopping accumulation

The invention discloses a random radiation radar imaging method based on inter-pulse frequency hopping accumulation, and the method comprises the steps: generating a series of pulses with different transmission frequencies, carrying out the sampling and corresponding accumulation of pulse signals, enabling a new radiation field matrix which is rearranged after accumulation to meet the orthogonal distribution of amplitude and phase through the configuration of an amplitude phase matrix in advance, and finally, performing inversion on the echo information and the radiation field matrix obtained after accumulation to obtain target information. According to the method provided by the invention, information of different frequencies is correspondingly accumulated and then is combined with amplitude phase frequency hopping configuration, so that a radiation field matrix rank can break through along an array element dimension, the irrelevance of the radiation field matrix is enhanced, and higher imaging performance i
