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
