摘　　要：提出了一种基于脉冲重复周期(PRI)跟踪器的已知雷达信号分选方案。介绍了已知雷达信号分选电路的组成部分。详细阐述了滤波电路、跟踪器首脉冲捕获电路和重频跟踪电路的实现方法。在FPGA上采用多路重频跟踪器实现多路信号并行分选。全硬件跟踪分选已知雷达信号,实现了密集信号环境下已知雷达信号的实时分选,提高了可靠性、灵活性和电子对抗设备的信号分选和处理能力。A known radar signal sorting scheme based on pulse repetition interval（PRI） tracker is given, and the integral part of the circuit is introduced. The method to realize the filter, the first pulse capture circuit and the PRI tracker are elaborated in detail. Multi-channel PRI tracker is mainly realized in FPGA for parallel signal sor- ting. The realization of whole hardware known radar signal sorting, realize the real time known radar signal sorting in high pulse dense signal environment, the reliability and flexibility are improved. The signal sorting and process- ing ability of the electronic warfare device is enhanced.
