摘　　要：讨论了在现代密集复杂的电磁对抗环境中实现雷达信号分选预处理的三参数关联比较技术和FIFO缓冲电路的设计,介绍了已实现的纯硬件三参数并行关联比较器的内部原理和具体实现过程,并分别通过Altera公司的QuartusII和Mentor Graphics公司的Model Sim专业软件仿真验证了设计的正确性,基本上实现了雷达信号的纯硬件快速预分选,达到了实时性和可靠性的要求。最后介绍了分选预处理器在电子战中的三种应用:威胁信号检测、无用信号滤波和脉冲重复频率选择滤波。The paper discusses three related-parameters comparing method and the design of FIFO for presorting of radar signals in the present complicated electromagnetic circumstance, and introduces the internal principle of the pure hardware comparer and its implementation. Both are verified using simulation by the professional softwares of the Altera company and the Mentor Graphics company. The correctness of the design is basically realized and its high performance is shown. At last, the paper also presents three different applications of the sorting processor to electronic warfare： detection of threating signal, filtering of useless signal and PRF selection filtering.
