A space target recognition algorithm based on structure feature is suggested in this paper. One-dimensional range profile of satellite is symmetrical due to symmetrical property of satellite structure, but one-dimensional range profile of debris is asymmetrical due to asymmetrical property of debris structure. Firstly location and amplitude of strong scatter centers of target are extracted using RELAX algorithm, then symmetrical property of strong scatter centers is tested according to two methods named pattern match and symmetricity measure and satellite and debris are recognized. Good recognition effect of this algorithm is shown by finally computer simulation experiment.
