The increasing of mobility of radio users requires more strict electromagnetic environment in low interference situation. The ground-based UHF/VHF chain monitoring network can provide the protection for high speed mobile radio users. The network should discover potential interference around surrounding path, and improve coverage. According to simulation calculation method and calculation formula, the theo-retical station distance is 10~25 km under the condition of straight line of ground-based chain monitoring stations,which provides reference for design of the network in the future.%无线电用户移动性的增加对低干扰的电磁环境提出了更高的要求。陆基链式超短波监测网可以为高速移动的无线电用户提供这种保障。该网络在用户移动路线周边布站,及时发现判定路径周边的干扰隐患,可以提升保障覆盖范围。通过设计仿真测算方法和计算公式,在设定的仿真条件下计算出直线线路条件下陆基链式监测站的理论布站距离为10~25 km,为今后该网的设计提供了参考依据。
