根据层次分析法的决策思想，提出了一种红外成像仿真可信度评估的综合算法模型。建立红外成像仿真可信度评估的层次结构评价指标体系模型，采用统计分析或专家打分确定各指标的可信度，利用和积法计算评价指标体系中每个可信度评估因素的权重，对各种可信度评估因素加以综合，得到客观量化的红外成像仿真可信度。理论分析和研究结果表明提出的方法能够对不同应用的红外成像仿真结果进行可信度评价，评价结果与实际红外成像具有较好的一致性。理论分析和可信度评价结果证实了此方法的合理性和有效性，为仿真用户提供了科学的决策依据。

The infrared imaging simulation credibility evaluation model is proposed based on the decision making thought of analytic hierarchy process. The index system to evaluate the infrared imaging simulation credibility is established. The indexes′ credibility is obtained by applying the statistic analysis or expert′s graded approach. The sum and product method is used to calculate the credibility evaluation factors′ weight. Then the objective quantitative credibility of infrared imaging simulation is gained by considering all credibility evaluation factors comprehensively. The results of research and theory analyzing demonstrate that the proposed method can evaluate the credibility of infrared imaging simulation, and the evaluation result is well consistent with actual infrared image. Theory analysis and the evaluation result of credibility shows the method is reasonable and efficient, and the scientific decision basis is afforded to the simulation users.
