一、引言地面初级辐射定标是红外空间遥感系统研制过程中的一项重要工作。所有的红外遥感仪器,其测量结果及其有效性必须严格建立在数据定量化的基础上,在使用之前,都必须经过地面定标。空间红外遥感系统的辐射定标,是一件非常困难和复杂的工作。涉及的方面有:初级与飞行定标技术、标准的建立与传递、定标理论与概念、各种源的制作和评价、源辐射理论分析、定标真空设备的研制、误差校正、源温度 I. INTRODUCTION Ground primary radiation calibration is an important work in the development of infrared space remote sensing system. All infrared remote sensing instruments, the measurement results and its effectiveness must be strictly based on the basis of quantitative data, before use, must be ground calibration. Spatial infrared remote sensing system radiation calibration is a very difficult and complicated work. Involved in: primary and flight calibration technology, the establishment and transmission of standards, calibration theory and concepts, a variety of sources of production and evaluation, source radiation theory, calibration of vacuum equipment development, error correction, source temperature
