In this paper, we address the method of subband implementation for wideband radar clutter sup- pression and target High resolution range pro¯le (HRRP) enhancement. The Doppler dispersion is overcome by separate weighting processing in the individual subbands. The optimal weight vectors are obtained by minimizing the Mean square error (MSE) between the reconstructed target HRRP and the actual target HRRP. The MMSE weight vectors require the actual target HRRP as a prior knowledge and cannot be implemented in practice, as a compromise the Minimum variance distortionless response (MVDR) weights are used. Several simulation results are given to illustrate the enhanced performance of target HRRP obtained by the methods proposed in this paper.
