摘　　要：脉冲分选技术是雷达对抗领域的一个十分重要的研究课题。针对直方图统计法估计PRI容易出现谐波问题和PRI变换法估计PRI运算量较大难以满足实时性要求的问题,提出了一种改进的脉冲分选算法,并采用多DSP并行处理的方法提高脉冲分选的处理速度。实验结果证明,提供的脉冲分选技术可以满足脉冲分选实时处理的要求。Pulse deinterleaving technology is an important research subject in radar countermeasures.The harmonic problem can be easily caused when the histogram statistics method is applied to estimate the PRI.In addition,the amount of operation is too large to satisfy the real-time requirement by using the PRI transform algorithm.In view of this,an improved pulse deinterleaving algorithm is proposed,and the multi-DSP parallel processing method is also used to speed up pulse deinterleaving processing.The test results show that the pulse deinterleaving technology can meet the real-time processing requirements.
