A hybrid FDTD-SIE approach for radar imaging system simulation

This paper describes computer simulations of an ultra-wideband radar imaging system. The system is equipped with a multi-static antenna array and mounted on a forward-moving platform. We consider several target types, placed on ground surface or buried, and clutter from rough surface. This paper introduces a hybrid approach to the implementation of the radar transmitters, by replacing the physical antennas with equivalent currents sheets on a surrounding closed surface. The numerical results consist of large scale radar simulations in the presence of multiple targets embedded in a rough ground environment.
