一种空中红外多目标威胁度排序方法

A Threat Sequencing Method for Aerial Infrared Multi-Target

针对红外序列图像中获取空中目标信息的特点,选取了威胁度排序所需的指标参数,并确定了各自的威胁隶属度函数。通过分析传统层次分析法中判断矩阵的构建和权重的变化,提出了一种改进的层次分析法用于多目标威胁度排序。该方法运用模糊判断矩阵的形式进行一致性处理,从而简化了一致性调整,为快速排序打下基础;同时,结合实际客观数据的变化进行修正各因素的权重,避免了排序过程中主观因素的偏差。试验计算结果表明,这种方法计算简单,主观因素干扰小,能真实反映目标的威胁程度,有利于辅助指挥员进行正确的决策。

Based on the characters of aerial target infrared information,the threat degree sequencing parameters is selected,and the function of the threatened menbership is confirmed.Therefore an advanced Analytic Hierarchy Process（AHP）is which is used for multi-targets threaten degree sequencing is gotten by struction of decision matrix and the variation of weight through analytic hierarchy process. This method carries out the consistent processing by fuzzy decision matrix in order to simplify the adjusted consistency,and finally the speed of sequencing is improved; meanwhile,according to the change of objective data,various factors have been amended to avoid the deviation of the subjective factors during sequencing. At last,the experimenting demonstrates that this method is very effective,objectively reflecting the threat degree and also in favour of the right decision.
