| Abstract: | In this paper, making use of the orthogonal quadrature filters, we construct the orthogonal multiresolution of finite dimension inner-product space and the fast discrete wavelet transform (FDWT). and reduce radar data storage by the transform. The methods of correlation and nearest neighbour classification in wavelet domain based on the compressed data are presented. The computation is faster in the methods of transformation domain Identification. The experiment results show that the methods are efficient and the data in wavelet transformation domain can more efficiently describe targets with reduced dimension. |
