Abstract

A comparison between the statistics of SAR images obtained by two different methods is presented. The first method uses a complete nonlinear velocity bunching phenomenon mechanism, whereas the second method uses only the second order Volterra Model approximation of this mechanism. This last model can be easily analyzed by the third order moment spectrum
