Abstract

The Michigan microwave canopy scattering model (MIMICS) was developed to simulate microwave backscattering from tree canopies. It is a simulation solution of the radiative transfer equations. The tree canopy is modeled as two horizontal vegetation layers over a dielectric ground surface. We modify MIMICS to accommodate the simulation of bistatic canopy scattering. Two angle parameters are added to specify the scattered direction. More types of extinction, source, and phase matrices, and ground reflectivity matrices are calculated. We present and analyze the bistatic scattering simulation results of several canopy coverages.
