Abstract This paper,at first ,expounds the relation between the singular singal and the modular maximum for wavelet transform,and the different features of singal and noise in wavelet transform.Then,in the light of high-resolution radar target one dimensional range profiles,it is decomposed in multi-resolution and the multi-resolution feature description are obtaiend.According to the multi-resolution feature description of radar target,the conception of difference degree for the range profiles is defined.Using the difference degree,the fast matching for target recognition can be obtained.
