摘要 针对电子支援措施(ESM)的技术要求,分析了ESM信号处理机的主要技术特点,提出了基于信号预处理和信号主处理的两级工作方式,并利用典型算法说明了ESM信号处理机组成及工作原理。给出了以未知信号预分选、已知信号预分选、脉冲重复间隔(PRI)分选、参数估计、雷达信号跟踪处理为主要模块的信号流程,并按模块的执行流程和原理组织了适合应用的硬件框架结构。 Aiming at the technology requirement of electronic support measure(ESM), this paper analyses the main technology characteristics of ESM signal processor, puts forwards 2-grade opera- tion modes based on signal pre-processing and signal main-processing,and uses typical algorithms to explain the composition and principle of ESM signal processor. The signal flow taking the un- known signal pre-sorting and known signal pre-sorting,pulse repetition interval(PRI)-sorting,pa- rameter estimation and the tracking and processing of radar signal as main module is given in the paper,and a suitable hardware architecture is offered according to the execution flow and principle of module.
