Interference suppression method based on motion compensation robust principal component analysis

An interference suppression method based on motion compensation robust principal component analysis relates to the technical field of underwater acoustic array signals, aims to solve the problem of low signal detection and estimation performance due to the influence of interference signals in seawater in the prior art, and comprises the following steps of: step 1, receiving underwater broadband signals and motion information of a sound source to be detected by using an array, wherein the broadband signal comprises a desired signal and an interference signal; step 2, performing motion compensation on the underwater broadband signals acquired by the array according to the motion information of the sound source to be detected; step 3, carrying out column vectorization on the compensated underwater broadband signals in the step 2; and 4, separating an expected signal and an interference signal in the underwater broadband signals after column vectorization by using a robust principal component analysis method.
