摘要
基于光线追踪的弹跳射线法存在射线管分裂的问题,而基于光束追踪的弹跳射线法根据目标几何结构动态划分射线管,可以有效改善射线管分裂并提高计算精度。本文根据介质和介质、介质和理想导体的边界条件推导出了无限大、金属衬底多层涂覆的反射系数矩阵,然后通过Stratton-Chu方程的高频近似式计算多层介质涂覆金属目标的RCS。与商业软件CST的快速多层多级子方法相对比,验证了算法的正确性及高效性。
Shooting and bouncing ray method(SBR) may give rise to the split ray tube problem, however, Shooting and bouncing ray method based on beam tracing(SBR-BT) can efficiently solve the problem by dynamically dividing the ray tube according to the geometry of the target. In our method, the reflection parameter matrix is obtained using the boundary condition. Compared with the full-wave simulation result from CST, SBR-BT has proved its accuracy and efficiency.
