分布式电力应急救援指挥网跳频信号时差定位方法

Time Difference Location Method of Frequency Hopping Signal in Distributed Power Emergency Rescue Command Network

针对跳频信号时差定位准确度较低且定位时间较长的问题,设计了一种分布式电力应急救援指挥网跳频信号时差定位方法。构建跳频信号时差定位模型,计算应急救援指挥指令信号的活动模式函数,实现分布式电力应急救援指挥网跳频信号时差定位。实例分析结果表明,设计方法的均方根误差低于10 dB,定位时间低于5 min,能够保证分布式电力应急救援指挥网应用过程的实时性,为分布式电力应急救援提供帮助,保障通信过程的完整性。

Aiming at the problems of low accuracy and long positioning time of time difference location of frequency hopping signal,a time difference location method of frequency hopping signal in distributed power emergency rescue command network was designed.Construct a time difference positioning model of frequency hopping signal,calculate the activity mode function of emergency rescue command signal,and realize the time difference positioning of frequency hopping signal in distributed power emergency rescue command network.The example analysis results show that the root mean square error of the designed method is less than 10 dB,and the positioning time is less than 5 min,which can ensure the real-time application process of the distributed power emergency rescue command network,provide help for distributed power emergency rescue,and ensure the integrity of the communication process.
