Abstract

The authors comment upon some simulations of the SAR imaging process obtained by using, firstly the complete nonlinear transform (i.e. the velocity bunching), and secondly its second order approximation (i.e. a second order Volterra model), in order to study the quadratic nonlinear interaction strength and localization and to compare with results obtained on ERS-1 images
