Radar Cross Section Analysis of Large PEC Structures Using LBVH Traversal

In this study, the radar cross-section (RCS) of a large structure is analyzed using linear bounding volume hierarchy (LBVH), which representative acceleration algorithm ray-tracing technique. A technique, high-frequency method, used to analyze electromagnetic properties structures, and (BVH), binary tree structure, applied reduce intersection search time. The improvement in calculation speed quantitatively by dividing an arbitrary scatterer into several triangles. results are compared with those multilevel fast multipole method (MLFMM) ray-launching geometrical optics (RL-GO) Feko commercial software verify accuracy. proposed technique can be utilized for efficient RCS calculations structures.
