Abstract :
This paper summarizes the most important results obtained by the 2D simulations of the decomposition of the SAR ocean imaging process over the Volterra models. These models allow a quite simple nonlinearities analysis from the point of view of nonlinear energy quantification but also for the phase coupling detection (i.e. nonlinearity detection) by using higher order spectrum (HOS) tools
