Abstract

We present a technique to extract the three-dimensional (3-D) bistatic scattering center model of a target at microwave frequencies from its CAD model. The method is based on the shooting and bouncing ray (SBR) technique and is an extension of our previous work on extracting the monostatic 3-D scattering center model of complex targets. Using SBR, we first generate the bistatic 3-D radar image of the target based on a one-look inverse synthetic aperture radar (ISAR) algorithm. Next, we use the image processing algorithm CLEAN to extract the 3-D position and strength of the scattering centers from the bistatic radar image. We test the algorithm by extracting bistatic 3-D scattering centers from several test targets and reconstructing bistatic signatures (RCS, range profile, ISAR imagery) using the bistatic scattering centers.
