Abstract :
In this paper, we are mainly concerned with the application of orthogonal discrete wavelet transform in feature extraction for incoherent radar ship target recognition, based on the Daubechies´ wavelets (1988). Experiments are carried out for the proposed method with practical video-echo data of four kinds ,and the corresponding results indicate that the computational complexity of the new method is small and the extracted features are typical with high data compression. In the last, a new detection approach to the odd video-echo of radar ship target is proposed
