Abstract:

Simulation of desert scene for land clutter radar cross section (RCS) is investigated in the paper,based on triangular facet model,an angular cutoff model of revised GO Model and γ-f  Model for backscattering coefficient and Digital Elevation Model (DEM) data of desert scene.The RCS matrix charts obtained by scattering characteristic model and geometric model of the scene demonstrate that the simulation results coincide mainly with special terrain features and periodic characteristics of the desert scene.The validity of the proposed model is then obtained.

Key words: desert scene;DEM;triangular facet model;radar cross section
