摘　　要：以FH-GMSK(frequency hopping-gaussian filtered minimum shift keying)通信系统作为载体对跳频通信的干扰样式识别进行研究,从跳频通信接收信号中联合提取干扰的时域、频域和时频域特征,得到了一组稳定性好、对干信比不敏感的特征参数,在不需要干扰先验知识的情况下对FH-GMSK通信系统中常用的干扰样式进行了自动识别。仿真结果表明:该方法对跳频通信常见的干扰信号在不同干信比的情况下能获得很高的正确识别率。This paper focuses on the interference recognition of the frequency hopping-Gaussian filtered minimum shift keying （FH-GMSK） communication system. Based on the interference characteristics extracted from the received signals in the time, frequency and time-frequency domains, a set of characteristic parameters was obtained. The parameters were robust and insensitive to the jamming to signal ratio（JSR）, so that the interferences could be automatically identified without need of prior knowledge. The simulation result shows that the method can be used to obtain a much more accurate recognition of common interfering signals in the FH communication system under the conditions of different JSR.
