针对分布式交互仿真中电波传播的建模与表现方法进行了研究。针对电波传播环境的复杂性,采用了一种将经验模型、半确定半经验模型和确定模型相结合的电波传播模型,并给出了复杂电波传播环境下相关环境信息数据的表达方法。在小区制非可视传播环境中,加速改进了基于SBR的射线跟踪算法,给出了相关的实验,并验证了其有效性。

英文摘要：

The modeling and representation method of electromagnetic wave propagation in distributed interactive simulation were researched. Considering the complexity of the electromagnetic wave propagation environment, a wave propagation model was adopted which was composed of empirical model, deterministic model and half-empirical half-deterministic model, and an expression technique for environment information data in complex electromagnetic wave propagation environment was given. The ray tracing algorithm in micro-cell and nonvisual environment was accelerated which was proved the validity by the experiment.
