民用航空测距信号对北斗导航信号的干扰研究

摘要

It is inevitable that Beidou navigation satellite system is interfered by various wireless equipment, during the progress of the system’s application and promotion, it is a problem that its signals are interfered severely by the aeronautical distance measurement signal. This dissertation introduced the frequency utilization status and the characteristics to the Beidou signal and the aeronautical distance measurement signal, provided an evaluation method for pulsed interference from aeronautical distance measurement signal. The conclusion can be a reference to the protection policy in the future.%北斗卫星导航定位系统不可避免地受到各种无线电设备的干扰，其中民用航空测距信号对北斗导航信号的干扰成为北斗应用推广中的一大问题。分析了北斗卫星导航信号和民用航空测距信号对频率资源的使用情况和信号特点，提供了适用于民用航空测距信号的脉冲干扰计算模型和干扰效果评估方法，为北斗导航信号的干扰评估和频率保护提供参考。
