Abstract
In one aspect, a method to generate radar signatures for multiple objects includes performing in parallel a shooting and bouncing (SBR) technique to solve for physical optics and multi-bounce characteristics of a plurality of objects in motion, a physical theory (PTD) technique to solve for material edges of the objects and a incremental length diffraction coefficient (ILDC) to solve for material boss/channel. The method also includes coherently integrating the results from the SBR, PTD and ILDC techniques by frequency and generating the radar cross section (RCS) values of the plurality of objects. Performing the SBR technique includes evaluating rays independently.
