间歇采样转发干扰是一种针对相干雷达的有效干扰样式,该类干扰的抑制技术研究需求迫切,而干扰识别历来是抗干扰流程中的关键环节,针对间歇采样转发干扰的识别问题,提出了一种基于关联维数的干扰识别方法。通过对3类间歇采样转发干扰信号进行傅里叶变换,挖掘信号频谱上的差异,提取频域关联维数作为干扰识别的特征参数,并利用支持向量机进行分类识别,为后续雷达系统采取针对性抗干扰措施提供重要的决策信息。仿真结果证明该方法具有较高的识别率。
Intermittent sampling and forwarding interference is an effective interference pattern for coherent radar. Research on this type of interference suppression technology is in urgent demand. Interference identification has always been a key link in the anti-interference process. For the problem of intermittent sampling and transmission interference identification, Interference Identification Method Based on Correlation Dimension. Through the Fourier transform of the three kinds of intermittent sampling and forwarding interference signals, the differences in the spectrum of the signals are excavated, the frequency-domain correlation dimension is extracted as the characteristic parameter of the interference identification, and the classification is carried out by using the support vector machine, Sexual anti-interference measures provide important decision-making information. Simulation results show that this method has high recognition rate.
