摘　　要：红外探测器响应特性漂移严重影响成像质量和系统性能。针对红外探测器响应特性漂移缺乏有效评价指标、难以建模和评价的问题,本文将红外探测器输出的序列图像看作时间序列数据,基于时差图像定义漂移度和漂移熵评价指标,用于评价红外探测器响应特性漂移程度,并提出了一种基于时间序列预测的红外探测器响应特性漂移评价方法。采用仿真数据和真实数据进行实验,结果表明,本文提出的漂移度和漂移熵评价指标可以有效度量响应特性漂移程度,所提出的评价方法可以实现对红外探测器响应特性漂移的建模和有效预测评价,研究工作可用于辅助选择合适的红外探测器及其非均匀性校正算法以提高红外成像系统性能。The response characteristic drift of infrared detector seriously degrades the imaging quality and system performance.Aiming at the lack of effective evaluation index and difficulty in modeling and evaluating the response characteristic drift of infrared detectors,the sequence image output by infrared detector is regarded as time sequence data,drift degree and drift entropy are defined based on time difference image to evaluate the drift degree of infrared detector response characteristics,and a method for evaluating the drift of infrared detector response characteristics based on time sequence prediction is proposed.Simulation data and real data are used for experiments.The results show that drift degree and drift entropy can effectively measure the drift degree of infrared detector response characteristics,and the evaluation method can establish the response characteristic drift model of infrared detector and realize prediction and evaluation.The research work can be used to help select appropriate infrared detectors and it’s nonuniformity correction algorithm to improve the combat performance of infrared imaging systems.
