摘　　要：电子通信技术最关键特点在于故障危险性高,若电子出现通信障碍,影响范围通常较大。为进一步优化网络通信的抗干扰性能,抵御外来信号的干扰,提出一种电子通信突变非线性多频干扰检测方法。引入调频连续波(Frequency Modulated Continuous Wave,FMCW)原理计算不同信号的之间的距离和移动速度,圈定电子通信突变信号范围,筛选出电子通信过程中的突变非线性多频干扰。采用Wigner-Ville分布对全部多频干扰信号展开谱图变换处理,获取干扰信号真实标签,同时构建突变非线性多频干扰信号对应的谱图。通过卷积神经网络提取谱图特征,将获取的特征向量输入到长短期记忆网络中检测,实现电子通信突变非线性多频干扰检测。实验测试结果表明,提出方法下干扰检测耗时在20ms内,不会受到通信内容长度阈值以及相似内容覆盖阈值波动影响,漏检率始终低于1.0%。The most important feature of electronic communication technology is the high risk of failure.In order to further optimize the anti-jamming performance of network communication,this article puts forward a method of detecting abrupt nonlinear multi-frequency interference in electronic communication.The Frequency Modulated Continuous Wavec(FMCW)principle was introduced to calculate the distance and speed between different signals and determine the range of abrupt signal,thus screening out the abrupt nonlinear multi frequency interference during electronic communication.Then,Wigner-Ville distribution was used to transform the spectrograms of all multi-frequency interference signals,thus obtaining the true labels of interference signals.Correspondingly,a spectrogram of abrupt nonlinear multi frequency interference signals was constructed.Meanwhile,spectral features were extracted by convolution neural networks,and then the feature vectors were input into the long-term and short-term memory network for detection.Finally,the detection of abrupt nonlinear multi frequency interference in electronic communication was completed.Experimental results show that the interference detection cost less than 20ms,and the method is not affected by the fluctuation of the communication content length threshold and the coverage threshold of the similar content.And the missed detection rate is always less than 1.0%.
