Method and device for removing interference in signal, magnetic resonance system and storage medium

The embodiment of the invention discloses a method and device for removing interference in a target motion signal, a magnetic resonance system and a storage medium. The method comprises the steps of carrying out interference elimination on the target motion signal received by a plurality of channels through employing an anti-interference matrix to obtain an interference-removed signal, wherein theanti-interference matrix is obtained according the following method: for the target motion signal, data received by a plurality of channels in a set time period is obtained, and the data forms a reference matrix; a frequency correlation matrix is obtained according to the frequency of the current interference signal and the sample number of the data; an interference coefficient matrix is calculated by utilizing the frequency correlation matrix and the reference matrix; and eigenvalue and eigenvector decomposition is carried out on the interference coefficient matrix, and an eigenvector with the maximum energy is remo
