Complex object's ISAR image simulation

This paper concerns the Inverse Synthetic aperture radar (ISAR) image of an object over a perfectly conducting ground plane or a lossy dielectric such as sea water. The first step, the “shooting and bouncing rays” (SBR) is used to solve this problem. The next step, the wide signal bandwidths and synthetic aperture are used to resolve objects rotating about an axis normal to the line-of-sight into two-dimensional resolution cells. The results indicate that this method can efficiently get the backscattering data, and can be used to get the simulation of Synthetic aperture radar image.
