摘要：

高密度复杂信号环境下的信号分选处理技术,是新一代雷达侦察系统信号处理的关键技术,也是雷达侦察领域一个亟待解决的问题。文中讨论基于脉冲重复间隔(PRI)的脉冲信号分选算法,首先建立脉冲到达时间(TOA)数学模型,然后在总结脉冲信号分选的SDIF直方图算法、传统PRI变换算法和修正PRI变换算法优缺点的基础上,提出了一种综合的脉冲信号分选算法,并对该算法进行了完整的仿真,仿真结果表明,该算法对综合算法可以提供可靠的参照。

Abstract:

The de-interleaving method of radar signal in the high density and complex signal environment is not only the key technology of the signal processing techniques of the new generation reconnaissance process systems,but a subject urgent to be solved in this field.This paper introduces the very reconnaissance algorithm which is based on the PRI.In the paper,the math model of TOA is established first,and then a comprehensive reconnaissance method is proposed and the computer simulation result is given based on the SDIF,conventional PRI conversion algorithm and the revised PRI method as well.Simulation results show that this algorithm can be a reliable reference for the comprehensive algorithm.
