SAR imaging of the ocean surface: nonlinearities simulation and estimation

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.
