为了做好卫星数据应用的技术储备,多角度偏振遥感相机DPC航空预研版已经研制成功并完成了航空飞行实验.DPC相机用于获取地气系统反射的偏振、多角度的太阳辐射信息,其地气物理参数反演依赖于定标的精度.偏振相机的辐射定标包括强度和偏振两个方面.本文研究偏振遥感相机的偏振参数的在轨定标原理与方法.基于偏振遥感相机的设计原理,以相机的偏振辐射模型为基础,探索偏振定标的原理和方法.使用DPC航空遥感实验数据,初步实现了在轨偏振定标并对定标结果进行了分析.为将来我国自主星载偏振遥感数据处理和在轨偏振定标提供理论基础.
In order to make good use of satellite data, the DPC Aviation Pre-Research Edition has successfully developed and completed the flight experiment.DPC camera is used to obtain the polarization and multi-angle solar radiation information reflected by the geo-gas system, The inversion of geophysical parameters depends on the precision of calibration.The radiation calibration of polarization camera includes two aspects of intensity and polarization.This paper studies on-orbit calibration principle and method of polarization parameters of polarization remote sensing camera.Based on the design of polarization remote sensing camera Principle and method of polarimetric calibration based on the polarization model of the camera.Using DPC aeronautical remote sensing experimental data, the calibration of on-orbit polarization and the calibration results were initially carried out.For the future of China’s autonomous satellite Polarization remote sensing data processing and on-orbit polarization calibration provide the theoretical basis.
