极化SAR相干斑抑制方法研究

his paper describes several ways to suppress speckle. In order to take full advantage of the different polarization-channel SAR images the relationship between the speckle noise suppression to achieve the purpose of using the polarization method of whitening filter area of the experimental data processing filter. More data channels for multi-polarization, SAR resolution to increase the amount of data led to a sharp increase, as well as the inadequacy of conventional filtering method, this paper presents a large image Lee adaptive polarization filtering and Gaussian filtering, based on anisotropic diffusion equations of filtering, polarization filtering comparative analysis of white.
