A Method of Fast Detecting Sequence for Stable Pulse Repetition Interval
-
摘要: 针对脉冲混迭造成的脉冲重复间隔(PRI)固定序列检测以及PRI估计困难的问题，该文提出一种基于平面变换的PRI固定序列快速检测方法。该方法通过脉冲到达时间(TOA)对平面宽度的整数取余运算，只需1次时域变换处理即可生成PRI固定序列平面变换点迹的周期性图形(PGPTP)；之后依据点迹图形模式的差异实现多个TOA交错的PRI固定脉冲序列的判定，并结合点迹图形纵向展开周期和平面宽度逐一估计出PRI值，进而实现密集信号环境下PRI固定脉冲序列分选。仿真实验验证了该方法的有效性以及高效、实用等优点。Abstract: In light of difficulties in detecting stable Pulse Repetition Interval (PRI) sequence and estimating its PRI in interleaving pulse stream, a fast detecting method based on plane transformation is proposed to solve the above problems. By one time-domain transform, the Periodic Graph of Plane Transformation Point trace (PGPTP) mapping pulse sequence with stable PRI is formed via the presented method performing integer remainder operation on pulse Time Of Arrival (TOA) over plane width. According to the differences in pattern of PGPTP got previously, pulse sequences with stable PRIs interleaved in TOA can be distinguished, and then the stable PRIs are got with point trace longitudinal deployment period and plane width and are therefore used to accurately deinterleave such sequences in dense pulse stream. Simulation results show that this method is valid and possessed of advantages such as high efficiency and practical applicability, etc.
