Radar cross section computation and visualization by shooting-and-bouncing ray (SBR) technique

Abstract

An effort is being made to develop an analysis model with sophisticated graphic capability for analyzing and visualizing the electromagnetic scattering from a complex radar target. This analytical model uses a hybrid technique of the shooting and bouncing ray (SBR) method and the physical theory of diffraction. Coupled with computer-aided design graphics, the model provides a capability for visualizing, analyzing, and interpreting the complex radar scattering phenomena via dynamic ray-picture displays on a computer graphic terminal. With its sophisticated ability to rapidly conduct visual diagnostic studies of radar scattering sources and multiple reflections from a complex target, the SBR model provides an efficient and cost-effective way of performing many practical RCS (radar cross section) analysis, design, and reduction applications that may not have been feasible in the past. In addition, this method can be used to complement experimental measurements in maintaining the quality assurance of the test data measured.<>
