　　根据确定性传播模型，在地理信息系统的基础上，实现了一种基于HLA技术的超短波通信仿真系统。仿真系统包括超短波(VHF)收/发电台、电波传播算法模型、仿真控制等模块，各节点通过RTI（运行支撑环境）构成了一个分布式仿真结构，可实现超短波通信系统的点对点通信、点对面通信、多套电台组网通信的性能仿真。并给出了在某典型场景中超短波电台语音传输质量、数据传输质量的仿真结果，同时给出了在不同位置布设电台的传播损耗分布。

A HLA-based VHF communication simulation system is proposed and implemented, in accordance with path-specific propagation prediction model and GIS. This system is composed of VHF transmitter/receiver station, radiowave propagation model and simulation control and other modules, and various nodes, through RTI, construct a distributed interactive simulation structure. With this system, the performance simulations of point-to-point communication, point-to-multipoint communication and multistation networking communication could be easily achieved. Some simulation results of voice and data transmission quality with VHF transmitter/receiver station in a typical scene are given, including propagation loss of various radios deployed in different locations.
