The composite scattering between dielectric sea surface and a conducting plate above it is calculated by using Physical Optical method and reciprocity theorem. Meanwhile, the dependence of the plate size on the composite scattering field is considered. The Doppler spectrum and the chaotic characteristic for the time series of composite scattering field are analyzed. Finally, artificial neural networks and wavelet analysis are introduced into the study of the sea clutter to realize the purpose of target detection, the factors which affect the detection of the target are discussed and the solutions to these problems are given.
