A study of radar backscattering on multi-scale bi-dimensional rough surfaces

The principal objective of the present work is to find an adequate description of natural rough surfaces in order to study backscattering from these surfaces and try in a future work to retrieve soil characteristic parameters. Previous work has shown the inadequacy of the classical description which considered rough surfaces as stationary random Gaussian processes. They proposed a multi-scale surface description considering one-dimensional surfaces and incorporated it into the integral equation model (IEM). We extend this multi-scale description to the bi-dimensional case using the Mallat algorithm and we investigate its impact on radar backscattering.
