description The invention belongs to the field of radar data processing, and discloses an SAR image sequence registering method based on movement platform parameters. The method comprises the following steps that a reference image and an image to be registered are obtained; a preliminary transformation image of the reference image is obtained according to the movement platform parameters; multiple closed areas in the image to be registered and the preliminary transformation image are extracted; the affine invariant moment feature of each closed area and the Euclidean distance and the inclined angle of the affine invariant moment feature are calculated; matching of the closed areas of the image to be registered and the preliminary transformation image is performed; transformation parameters from the image to be registered to the preliminary transformation image are calculated according to the matching result; the transformation parameters from the image to be registered to the reference image are obtained according to the
