摘要:

通道式偏振遥感器可获取目标光谱辐亮度、偏振度和偏振方位角等多维度信息,是目前最常用的偏振遥感探测的主要仪器类型之一。介绍了通道式偏振遥感器偏振定标的原理,根据矩阵光学理论和辐射度学理论,构建新的Stokes矩阵,从光谱维建立完善的偏振定标模型,分析了需要定标反演的参数,并给出了相应的定标方法,可为类似的通道式偏振遥感器的偏振定标工作提供参考。

Abstract:

Channel-type polarization remote sensor is one of the most common instruments in polarization remote sensing, which can obtain spectral radiance, the degree of polarization, polarization azimuth angle and other multi-dimensional information of the target. The polarization calibration principle of the channel type polarization remote sensor is described. A new Stokes matrix is built according to the radiometry theory and matrix optics theory. The polarization calibration model from the spectral dimension is established and improved, calibration retrieval of the parameters is analyzed, and the corresponding calibration method is introduced. It could provide a reference for similar channel-type polarization remote sensor polarization calibration work.

Key words: polarized remote sensing, polarization calibration, polarization remote sensor, channel-type
