为提高雷达脉冲分选效率以及将分选和辐射源识别统一完成,探索仅在时域进行重频分选与辐射源特征提取.将雷达脉冲序列的到达时间(TOA)在时间上进行折叠,使得交错在一起的雷达脉冲序列在TOA折叠平面上所形成点迹图.不同雷达由于重频特征不同使得属于一部雷达的脉冲在TOA折叠平面上的点迹形成较强的规律性.文中应用改进的方法通过对点迹的聚类来完成对上述规律的提取,实现将雷达脉冲分选和重频特性识别统一完成.

Pulse repetition frequency(PRF)deinterleaving and emitter characteristic acquisition accomplished in time domain are explored for improving the deinterleaving efficiency and at the same time finishing emitter characteristic acquisition with deinterleaving in one step.After the Time of arrival(TOA)folding in time domain for the radar pulse train,the plot of interleaved pulse can be got.Different curves are formed by the points corresponding to pulses from one radar in TOA folding plot for different PRFs.An i...
