RCS prediction using fast ray tracing in Plücker coordinates

Shooting and Bouncing Ray (SBR) method based on ray tracing is used in RCS calculation of arbitrary shaped targets in high frequency regime. Large targets are usually modeled by the usage of large number of triangles. In this study, for the purpose of the acceleration of ray-triangle intersection test, ray tracing in the SBR method is used in Plücker coordinates. Ray-triangle intersection test using Plücker coordinates is compared with the Möller-Trumbore and Badouel´s method currently available in the literature. It is demonstrated that solutions using Plücker coordinates can greatly reduce the computation time analysis of RCS.
