摘　　要：该文针对电子侦察信号盲分选的技术难题,结合重频参差调制模式的特点,提出基于数据统计聚类和关联匹配的处理方法,对序列中含有重频参差调制的脉冲进行调制模式识别、参差序列分析和脉冲提取。实验仿真表明在脉冲丢失和虚假脉冲干扰的情况下,所提方法可以有效进行重频参差模式识别和参差排定次序分析,实现脉冲信号的盲分选,具有较强的鲁棒性。To solve the technical problem of blind sorting of electronic interception signal, combined with the characteristics of pulse repetition interval stagger mode, based on the statistical clustering and data association, the algorithm for stagger pulse repetition interval pattern recognition is proposed, sequence analysis and signal sorting is carried out. The simulation results show that the proposed method can effectively dispose the blind signal sorting process and has strong robustness in case of missing and spurious pulses.
