| 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。 |

| Abstract: |
| 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. |
