Experiment and Simulation of Buried Targets in the Vicinity of Objects on the Ground with a Synthetic Aperture Radar

Investigation of imaging performance of buried targets in the vicinity of objects on the ground with a synthetic aperture radar is conducted with laboratory experiment and simulation. To conduct radar remote sensing of buried targets, influences from ground-based objects playa role on the performance. We implemented azimuth compression processing scheme from the output of the commercial FDTD software and successfully obtained the radar image of corner reflectors. We conducted simulation as well as laboratory experiment, and radar imaging of buried object in the vicinity of ground-based target showed that electro-magnetic blocking effect of the ground-based object influenced the imaging performance of the buried target.
