摘　　要：讨论了跳频通信信号的基本特征。通过对时域信号进行傅里叶变换计算出跳频信号的特征参数,实现对跳频通信信号的估计。根据实际通信对抗环境,将混合在一起的不同网台的跳频信号分选出来,完成跳频网台的分选。This article discusses the basic characteristic of frequency hopping communication signals. By means of Fourier transformation of time domain signal, the characteristic parameters of frequency bopping signal can be calculated and the signal can be estimated. According to the actual communication countermeasure environment, the frequency bopping signals of different networks that have been mixed together can be sorted out, which finishes the frequency hopping network sorting.
