Terrain clutter modeling for airborne radar system using digital elevation model

摘要

The modeling and simulation of radar clutter in the past mostly based on statistical models, this paper by using digital elevation model (DEM), give the clutter model for specific terrain environment, and generate the clutter simulation data. Under the clutter model using digital elevation model (DEM) of specific terrain, compute the radar cross section (RCS). According to radar signal echo equation, determine clutter simulation and generate the specific terrain clutter signal of airborne radar system. The simulation results show that clutter modeling and simulation using the digital elevation model (DEM) can reflect the non-homogeneity of the ground surface, so as to provide more precise clutter data for radar system simulation and signal processing.
