Decomposing the Non-Gaussian Surface in Sum of Gaussian Surfaces

摘要：

　　The decomposition of the multivariate Non-Gaussian PDF in the sum of a Gaussian PDF instead of the Gram-Charlier series is investigated.Four parameters need to be found by minimizing the integrated square of the difference between Cox-Munk function and its approximation.The backscattering radar cross section (RCS) of the surface is calculated by the Kirchhoff approximation (KA) under different value of k using the formula of decomposition of the Non-Gaussian.The condition of KA satisfying electromagnetic scattering scale from Gaussian and Non-Gaussian surfaces is taken into account by computing the backscattering coefficients in HH and VV polarity.
