基于序列关联的参差信号分选算法

For the conventional histogram signal deinterleaving algorithm's drawback of stagger signal, a histogram algorithm based on corresponding of pulse interval and single pulse is proposed. This algorithm utilizes the corresponding of pulse pair interval and single pulse to get a matrix named Pulse Interval Distribution Matrix (PIDM), and a novel histogram is obtained via cumulating row of the matrix. This histogram can avoid the suppressing of frame period of staggered pulse train caused by Pulse Repetition Intervals (PRI) transform algorithm when staggering signal deinterleaving, and can extract the subsequence of pulse train through PIDM. Simulation results show the algorithm has excellent performance on environment including multi staggered pulse trains with multi-fixed pulse trains under the circumstance of without adding the complexity of calculating.
