基于脉冲样本图的机载 RWR／ESM 辐射源威胁评估

摘要

Threat assessment of radiation source is an important function of airborne Radar Warning Receiver/Electronic Support Measure ( RWR/ESM ) .To improve the RWR/ESM ability in the complex electromagnetic environments,an expert system of threat assessment was established based on the pulse sequence pattern.The assessment index was determined taking the pulse sequence pattern as the input by using the power model of radar.The TOPSIS method was used to make the assessment system objective and effective,which can meet the requirements of Electronic Warfare and conform to the working process of airborne RWR/ESM.The simulation proved that the assessment system is effective and feasible.%辐射源威胁评估是机载雷达告警器／电子支援措施（ RWR／ESM）的重要功能，为了提高机载RWR／ESM设备应对复杂电磁环境的能力，建立了基于脉冲样本图的威胁评估专家系统，通过雷达威力模型确定了以脉冲样本图为输入的评估指标，运用TOPSIS方法，使得评估系统客观、有效，贴近电子战要求，符合机载RWR／ESM工作流程。仿真证明了评估系统的有效性及可行性。
