摘要
RWR/ESM系统中对于诸如"虚警"、"漏警"等概念,经常从理论上和应用上混淆。结合RWR/ESM系统实际信号处理流程和功能,从信号统计检测理论出发,对比雷达/通信相关概念,发现传统意义上的"虚警"、"漏警"已不足以描述RWR/ESM对威胁的检测识别错误,为此基于多元假设检验理论,结合信号威胁等级,重新梳理RWR/ESM系统中信号检测类型的概念,将RWR/ESM的"虚警"、"漏警"拓展为带威胁级差的"虚警"、"漏警",增加"同级差错"概念,并初步探讨其概率、代价因子等相关特性。
For RWR/ESM suites/systems, such concepts as ＂False Alarm＂, ＂Miss Alarm＂ are often confused in engineering operations and theoretic analysis. According to the theory of signal＇s statistical detection/classification, in combination with RWR/ESM＇ s signal processing flow and functions, and through comparing corresponding concepts of radar and communication, it is found that the traditional concepts of ＂False Alarm＂ and ＂ Miss Alarm＂ can not cover the error detection kinds in RWR/ESM system. So signal＇s detection kinds in RWR/ESM are re-teased combined with threating levels and based on multiple hypotheses testing. ＂False Alarm＂ and ＂Miss Alarm＂ of RWR/ESM are developed with threating level- differs, and ＂same threating level error＂ is superadded, the characters of related probability, cost genes and so on are discussed preliminarily.
