Abstract: Since the target High-Range-Resolution-Profile contains very important target discrimination structure information, it is regarded as a promising radar automatic target recognition(RATR) signature. It is known that the HRRP range alignment is a crucial problem in HRRP based RATR, which generally includes two kines of approaches, namely, absolute range alignment method and relative range alignment method. Based on a radar range profile absolute alignment method, Zero Phase Representation, an HRRP recognition approach based on the subband signal is proposed, which is robust to the range alignment error. Experimental results show the proposed method can lead to a good recognition performance with the advantage of low computation complexity over the maximum correlation coefficient (MCC) classifier, and outperforms the classifier based power spectrum feature.
