[0059] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0060] figure 1 It is a flowchart of a polarimetric SAR multi-component target decomposition method described in the present invention. This polarimetric SAR multi-component target decomposition method, on the basis of the previous four-component decomposition algorithm, adds an additional diffuse scattering mechanism that may come from terrain or rough surfaces as the fifth decomposition component, that is, the fully polarimetric SAR coherence matrix T Or the covariance matrix C is decomposed into a linear weighted sum of five scattering components including odd scattering, even scattering, volume scattering, helical scattering and diffuse scattering. The algorithm uses the improved NNED (NonnegativeEigenvalueDecomposition) method to solve the volume scattering power, and directly adopts the corresponding odd-order scattering, even-order scattering and diff...
