摘　　要：针对云闪定位系统,探讨了利用雷电信号到达探测站的时间和方向进行云闪定位解算的基本原理。应用蒙特卡罗法对云闪定位误差进行了仿真分析。通过不同高度发生的云闪和地面不同数目探测站的组合,分析了云闪定位精度在雷电信号探测精度相同的情况下与探测站和云闪点组成的图形有关。其结论有助于云闪探测网的优化设计与精度评定并在数据处理时进行优化解算。Aiming at the cloud flashing position system,we discussed the basic principle of cloud flashing position solving with the time and direction of the lightning signal arriving at the detection station.Then,we used the Monte Carlo method to simulate the error of cloud flicker.Based on the combination of cloud flashing at different heights and different number of ground station,we discovered that the accuracy of cloud flashing position was related to the pattern of flash point and the flash point of the lightning station.The conclusion is helpful to optimize the design and accuracy of the cloud flashing detection network,and optimize the solution when the data is processed.
