机载雷达告警系统中威胁等级判定方法研究

在机载雷达告警系统中,辐射源威胁等级判定对自动实施有效的干扰功率分配和提高作战飞机的生存能力至关重要。针对现在作战飞机所面临的多目标作战情况,利用模糊数学建立了威胁指标的隶属度模型,通过层次分析法和熵值法获得了各威胁指标的主观和客观权重,用综合赋权法融合了主客观权重,最后根据机载雷达告警系统的综合性能要求,建立了辐射源威胁等级判定函数,实现了对辐射源威胁等级的判定。通过实例应用说明了该方法能够有效地判定辐射源的威胁等级。

Research on threat level determination approach for airborne radar warning system

In airborne radar warning system, radiation threat level determination is very important to implement effective interference power distribution automatically and improve the viability of combat aircraft. For multi-target combat situation faced by modem combat aircraft, use fuzzy math establish threat index model. In the model, the subjective and objective weights of threat index are determined according to analytic hierarchy process and entropy method, using synthetic weighted mark method integrates subjective and objective weight. Finally, based on overall performance requirements of airborne radar warning system, establish radiation source threat level decision function and achieve radiation source threat level determination. It shows through examples the method is able to determine threat level of radiation source effectively.
