【摘要】 红外辐射定标是红外遥感信息定量化的关键技术之一。从我国空间红外传感器的发展要求出发,结合国外基于绝对低温辐射计的红外辐射定标技术研究状况,提出了利用宽波段可调谐激光器和球状InSb、HgCdTe光电探测器以及薄膜热电堆探测器TS-76来实现高精度中远红外辐射定标的技术方案。更多还原

【Abstract】 Infrared radiometric calibration is of critical importance for information quantification of satellite remote sensing of environment at infrared spectrum.In this paper we propose plans for laboratory calibration at middle infrared and far infrared spectrum for Chinese space sensors.We review and compare various advanced calibration techniques,and suggest calibration methods based on widely tuneable lasers,HgCdTe/sphere detectors,InSb/sphere detectors and thin-film thermopiles TS-76.Technical proposals are briefly discussed.更多还原
