Abstract Peak sequence matching is a important approach to SAR ATR. A general Gaussian model for peak is given in this paper and the extraction method is designed based on this model. Utilizing actual target database, the variability of target’s peaks with target orientation, configuration and depression angle is analyzed. The results show that the peaks of target in SAR image have some stability with target’s orientation, configuration and depression variability. So it is feasible to recognize target from SAR image using peak feature.
