摘要
传统的系统级网络仿真无法对复杂电磁环境中的战术通信网络参数进行实时精确计算。本文采用射线跟踪方法建立传播模型,根据绕射特性以及跟物体相关的反射、透射系数来评估电场、磁场,考虑野外不规则三维地形、地表材质、发射机/接收机/干扰源的天线辐射特性和朝向、载波频率等对电波传播的影响,精确计算出接收功率、路径损耗、到达时间以及到达角度等,从而实现对信道电波传播模型的精确刻画,模拟了复杂地形环境下的战术通信网络并对结果进行了分析和评估。
This paper presents a model of network nodes,equipments,protocols,businesses for tactical communication networks based on VRNET Developer.By making use of the ray-tracing method,a wireless electromagnetic propagation model and the simulation platform closed to the actual combat environment are built for the simulation of tactical communication networks.Based on specific scenario simulation,the impacts of complicated terrain and interference to the tactical communication networks are analyzed.The main goal of the study is to provide a way for the further research on tactical communication networks.
