为使热红外伪装检测指标能更加真实地体现目标的热红外伪装效果,进一步完善热红外伪装效果检测研究,针对目标在红外波段的温度暴露征候和红外图像暴露征候产生的原理及所表现出的特点进行了实验及数学分析,提出了合理化的热红外伪装效果检测指标.在具体的检测指标方面,讨论了目标与背景的平均温差检测指标的作用和局限性,并引入了辐射温度标准差对比指标,较好地解决了平均温差指标不能反映热图纹理的问题,此外,还对目标斑点暴露尺寸及红外图像直线边长度等热红外图像检验指标进行了讨论.

In order to reflect the effect of thermal infrared camouflage with the examination indexes of thermal infrared camouflage more truthfully,and to improve research on thermal infrared camouflage detection further,some experiments and data analysis have been carried out according to the signs and characteristics of targets reflected in the infrared band and infrared thermal images.Therefore,the paper proposes more rational examination indexes of thermal infrared camouflage.In the aspect of specific examination indexes,this paper discusses the function and limitation of mean temperature difference index between target and its background,and introduces the comparison index of radiation temperature standard deviation,then the problem caused by the mean temperature difference index which cannot reflect the texture of infrared image could be solved pretty well.Furthermore,this paper also discussed some examination indexes of infrared images such as:speckle size of target exposure,the length of straight lines in the infrared image.
