基于TOPSIS-AHP法的红外航空成像侦察相机综合评价

Comprehensive Evaluation of Aerial Imaging Reconnaissance Camera Based on TOPSIS-AHP Algorithm

根据红外航空相机的成像原理,提出了相机评估指标。通过层次分析法(AHP)求解得到各指标的权重向量,并运用逼近理想解排序法(TOPSIS)对相应指标进行计算,最后通过实例验证了该方法的可行性。计算结果表明,空间分辨率和温度分辨率是红外航空相机敏感度最高的两类指标,为今后相机的研制与改进提供了参考方向。

According to the imaging principle of an aerial infrared camera,the indexes for evaluating a camera are proposed.Then,the Analytic Hierarchy Process（AHP） is used to get the weight vector of each index and the Technique for Order Preference by Similarity to Ideal Solution（TOPSIS） is used to calculate the corresponding indexes.Finally,the feasibility of this method is verified in some examples. The calculation result shows that space resolution and temperature sensitivity are the two most sensitive indexes of an aerial infrared camera.This work is helpful to the development and improvement of aerial infrared cameras in the future.
