The invention relates to an interference suppression method based on multi-temporal coupling analysis, realizes interference suppression of remote sensing images in an image domain, and belongs to the field of radar signal processing. The remote sensing image has the characteristic of multiple time phases, and backgrounds of multiple remote sensing images in the same region have certain correlation, so that the backgrounds can be considered to meet the low-rank characteristic; and interference signals only appear in one or more images, so that the interference signals can be considered to meet the sparse characteristic. According to the method, the low-rank and sparse characteristic differences of the background and the interference of the remote sensing image are utilized to realize the separation of the background and the interference, the clear remote sensing image is restored, and the interference image is separated. Compared with a traditional interference suppression method, the method does not need to
