空中隐身目标威胁等级的仿真研究

Simulation Research of Air Stealth Targets Threat Grade

在多目标来袭的战场环境中,能够有效的评估出包括隐身目标在内的所有目标的威胁等级,是战场指挥决策系统中的核心部分。目前问题的难点在于雷达探测到隐身目标以后,如何将其数据信息进行量化分析用以反映目标的威胁等级,尤其是隐身目标的雷达散射截面积(RCS)。建立起层次分析法(AHP)基础,为了适用于隐身目标并改善原始判断矩阵的量化水平,提出了一种隐身目标威胁等级的改进方法。通过引入构造的隶属函数,不仅可以将所有目标的距离、速度和RCS信息进行量化处理并构造成判断矩阵,有效地减少了人为因素的影响。经过对一组不同类型目标的仿真分析,给出了各个目标的威胁等级。结果表明方法有效地评估出隐身目标的威胁等级,为防空火力发挥最大效能提供了依据。

In the multi-target attacking battlefield, the effective estimate of the threat grade for all targets inclu- ding stealth targets is the key point of the battlefield decision-making system. At present, the difficulty of the prob- lem is how to resolve the quantitative analysis to reflect the appropriate threat grade when the radar detects stealth tar- gets, especially the Radar Cross Section （RCS）. In order to apply to the stealth targets and improve the quantitative level of the original judgment matrix, based on the Analytic Hierarchy Process （AHP）, an improved method is pro- posed for the threat grade of stealth targets. Through the transformed membership functions, distance, velocity and RCS can be used to process and construct judgment matrix directly and the influence of human factors can be reduced effectively. The threat grade of different types of targets is given via simulation analysis. The results show that this method enhances the threat grade of stealth targets significantly and has better effectiveness.
