摘要

摘要:
针对当前雷达辐射源威胁评估对精确侦察数据依赖性较大的问题，提出一种基于行为特征的雷达辐射源威胁评估算法。从辐射源目标行为特征和数据融合理论出发，建立基于行为特征的辐射源威胁评估体系，并采用模糊理论和Vague数据集对各子行为进行表示；考虑到指标间的耦合性和空战的高动态性，利用改进的区间灰色关联度修正初始权重，建立以距离为自变量的态势状态函数，为各子行为动态赋权；采用改进的雷达图法计算威胁目标的威胁程度。仿真结果表明：所提算法具有较好的准确性和适应性。

Abstract:
This paper studies the problem that the current radar radiation source threat assessment algorithm relies heavily on accurate reconnaissance data. Firstly, a radiation source threat assessment system based on behavior characteristics is constructed, starting from the radiation source target behavior characteristics and data fusion theory. Also, fuzzy theory and Vague datasets are employed to represent each sub-behavior. A situational state function with distance as an independent variable is constructed by using the modified starting weight of interval gray correlation degree to solve the coupling between indicators and the high dynamics of air warfare. Finally, an improved radar map method is adopted to calculate the threat level of the threatening target. The simulation results show that the algorithm in this paper has good accuracy and adaptability.
