Abstract :
A coherent 3D model of wave scattering by a forested area is used to produce the data necessary to construct SAR images of the given field. Based on a domain integral representation of the scattered field, the model is applied, in VHF band, to a configuration where the separation between the trees is such that the coupling between the latters is weak. The computed backscattered field is used as an input to classical algorithms of SAR image reconstruction
