摘　　要：红外焦平面阵列探测器是目前红外目标探测的主要器件,为了从红外图像反演得到目标的辐射特性数据,通过对3～5μm中波红外焦平面的辐射特性测量方法进行了系统研究,给出红外辐射特性测量数学模型,建立红外辐射定标系统,确定实验室辐射定标的流程,进行辐射定标实验;利用MODTRAN大气传输计算软件,得到目标和红外探测系统之间的大气传输修正参数;进行辐射特性测量实验;结果表明,辐射特性测量精度优于10%,满足实际工程的需要。The Infrared focal plane array detector is the main device for infrared target detection. In order to get infrared radiance data from image, Research of infrared radiation characteristic measuring method based on the 3-5um medium was carried. Establish mathematical model of measurement of the infrared radiation characteristic, and set up infrared radiation calibration system, determine the laboratory radiometric calibration process, calibration experiment Using MODTRAN atmospheric transmission software, get transmission parameter between the target and infrared detection system; Take the radiation characteristic measurement. In this paper the results show that, the accuracy of radiation characteristics is better than 10% Satisfy the need of engineering.
