| Summary: | This thesis develops theory and algorithms for rapid simulation of the radar backscatter signatures of targets moving relative to a source/receiver. A geometric optics approach is used to estimate the radar return from a complex target surface described by functions which are almost everywhere curvature continuous. The method exploits the second-order continuity of the target modeling technique to reduce the problem of finding all the specular points associated with each new trajectory position to that of tracking the motion of existing points. In particular, it is shown that the locations of the annihilations and creations of multiple-bounce specular paths may be predicted for an entire trajectory, eliminating the need to search the whole surface for specular points as the target moves in relation to the source/receiver. In addition, the use of B-spline-like surfaces over arbitrary topological meshes is demonstrated as a technique for extending the results to work directly from existing faceted target models. |
