Improved Radar Signal Deinterleaving Algorithm Based on DTOA Histogram

Huang Guigen1,Fu Youguang1,Wu Yueting2(1.Nanjing Research Institute of Electronics Technology,Nanjing,210039,China;2.ZTE Corporation,Nanjing,210012,China)  
Pulse repetition interval(PRI) is one of the most important interpulse parameters in radar emitter pulse trains signal.Traditional cumulative TOA difference histogram statistical algorithms are studied and improvement is made.The statistics tolerance and the statistics threshold of the algorithm are analyzed theoretically.Mutil-statistical threshold is designed and applied to deinterleave pulse trains with stable or stagger PRI efficiently and correctly.The deinterleaving algorithm flow is designed,which combines the cumulative TOA difference histogram statistical algorithm with the sequence searching method.With controlling signal deinterleaving flow strictly,harmonic is decreased and the algorithm is efficient.Application on actual ECCM system shows that the improved algorithm is feasible.
