RCS computation of jet engine with complex termination based on multiplaten Z-buffer algorithm

The analysis of electromagnetic scattering from the jet engine with complex termination is a very difficult task because the electrical size of the engine cavity is very large and the geometry of engine termination is very complex. In this paper, the shooting-and-bounding rays (SBR) method is employed to analyse electromagnetic scattering from jet engines with complex termination. In order to accelerate the ray tracing and to economise the computation memory, the multiplaten Z-buffer algorithm is employed to model the jet engine. Two jet engine models with the complex termination are analysed. Excellent results are obtained for the two models.
