基于IFS的区域目标群威胁度评估

在已有的单目标对空威胁评估的基础上,提出了一种针对区域防空的威胁度评估方法。利用直觉模糊集处理模糊信息的优势,可以较好地处理由于传感器探测误差导致的模糊态势,克服在雷达探测过程中出现的误差。在属性权重完全未知的情况下,综合考虑了区域内目标重要性、防空措施以及目标本身抗毁伤能力,推导了权重求取公式。列出了威胁评估值的求取步骤。经过运算,由算例1到t时间后算例2在评估结果上的变化,验证了方法的有效性。

Threat Assessment of Group Targets in Protected Area Based on IFS

Basing on existing theory of assessing threat value of single target,a method of assessing threat value of protected area is proposed.IFS theory can deal with fuzzy information very well and overcome the error during collecting situation analysis.In the case of totally unknown weight,according to importance value,air defense measure and anti-damage ability,deriving the formula of weight. Steps of calculating threat value are listed. By solving example1 and after time t the example2,changes of the result of example 1 and 2 prove method of threat assessing in this paper is feasible.
