The technology research of pulse sorting based on high density environment

高密度环境下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。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。通过聚类的方法对高密度信号进行稀释处理,然后对稀释后的信号进行PRI分析,并且提供了一种基于4片DSP硬件平台的实时处理方案。最后通过仿真试验的方法论证算法的性能,并验证了实时处理方案的有效性。

The technology of pulse sorting based on high density environment is an important research field in radar countermeasures.An improved algorithm of pulse sorting is proposed,and the method of multi-DSP paral-lel processing is used to improve processing speed of pulse sorting.A method which dilutes the high density plus es based on a cluster is improved and then the pluses are aralyzed by the PRI.A real-time processing scheme based on the hardware platform of four pieces of DSP is given.The simulation experiment results have shown that the algorithm performance of pulse sorting and the Effectiveness of the real-time processing scheme.
