1. A computer comprising:
- a database including individual RCS data corresponding to each object from a plurality of objects, said computer system being programmed to compute the combined RCS signatures of said plurality of objects in a scene from the integration of individual RCS data, said computer system being further programmed to employ a ray tracing scheme to determine ray blockage and ray coupling as a result of object interaction.

Abstract
A method and system for analyzing the RCS of an object using N Point signature prediction models is provided. N-point signature prediction models are created for each object in a scenario and stored in lookup tables. Shooting and Bounce trace back techniques are used to determine RCS signatures of multiple objects in modeled scenarios to account for blockage by and coupling phenomena of a scattered field.

8. A computer programmable medium having computer-executable instructions for performing a method comprising:
- receiving individual RCS data corresponding to a plurality of vehicles;
computing a path, traced along one or more modeled rays, of a return radar signal from one or more vehicles to a point of origin of a radar signal incident upon one or more of said vehicles; determining whether the computed path would be obscured from one or more vehicles by one or more other vehicle from said plurality; and computing magnitude and phase data from a scattered field as presented by the return radar signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
