摘要
基于海空红外图像提出了海空大气模型,分析并研究了大气环境对红外热成像系统成像的对比传递函数。以红外热成像系统为例,对海空大气模型中斜程路径的大气对比传递函数进行了计算,分析了观测距离、大气密度、目标海拔高度、大气程辐射、路径天顶角对大气对比传递函数的影响。实验结果表明,大气传输路径的观测距离、大气密度、大气程辐射、天顶角与大气对比传递函数成反比。该结果可以用于预估实际应用时大气对红外热成像系统的影响,为提高红外热成像系统的成像性能提供基础。
Abstract
The sea-sky atmospheric model is proposed based on the sea-sky infrared image, and the contrast transfer function of the atmospheric environment on the imaging of infrared thermal imaging system is analyzed. Taking the infrared thermal imaging system as an example, the atmospheric contrast transfer function of the slant path in the sea-sky atmospheric model is calculated. The effects of the observation distance, atmospheric density, target altitude, atmospheric path radiation, and path zenith angle on atmospheric contrast transfer function are analyzed. The experimental results show that the observation distance, atmospheric density, atmospheric path radiation, and zenith angle of the atmospheric transmission path are inversely proportional to the atmospheric contrast transfer function. The results can be used to estimate the atmospheric impact during the practical application of the infrared thermal imaging system, and provide the basis for improving the imaging performance of the infrared thermal imaging system.
