提出了一种准光学光线跟踪模拟的运行时间优化方法。这些射弹射线法被用来评估环月通信链路中的多径衰落损耗。我们的方法采用了将月球地形图划分成近似菲涅尔区横截面的二维投影的形状。这种技术大大减少了计算运行时间，而不会导致显著的模拟精度损失。
A methodology is presented pertaining to the run-time optimization of quasi-optical ray-tracing simulations. These shooting-and-bouncing ray methods are used for assessing multipath fade loss in cislunar communication links. Our approach employs partitioning lunar terrain maps in shapes that approximate two-dimensional projections of Fresnel zone cross-sections. This technique drastically reduces computational run-time without causing significant loss of simulation accuracy.
