Research of Electromagnetic Wave Propagation Model in Distributed Interactive Simulation

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.
