| 摘 要： | 影响甚低频／低频（VLF／LF）通信效果的主要因素是雷电引起的大气噪声，其发生具有随机性，理论分析比较困难。文章利用噪声特征经典分析模型，采用其低通等效形式在Simulnk仿真平台下建立了仿真模型，并对大气噪声条件下的甚低频／低频（VLF／LF）通信系统误码性能进行了仿真研究。

| Abstract: | At very low frequency, atmospheric noise caused by thunderstorms is the principal factor that restricts the system performance. It＇s very difficult to analyze by theoretical methods because of randomness of thunderstorms. In this paper, a simulation model of VLF/LF communication system in atmospheric noise environment is propcsed using the classical model. The bit error rate （BER） performance of the system are obtained through simulation results. |
