| Abstract: | Main methods of underwater moving target dynamic spectrum feature extraction and enhancement such as correlation function method,adaptive line enhancement method,neural network method,wavelet transform method,chaos dynamics and fractal theory,higher order statistics method,and their research results are introduced and defects of these methods analyzed.It is worthy problem for discussion that underwater moving target dynamic spectrum feature extraction and enhancement be extracted and enhanced using higher order statistics in all introduced methods. |
