摘要:

偏振探测系统定标对于大气探测有着重要意义,是基于偏振探测的大气参数高精度反演的必要基础。中科院安徽光机所研制了星载大气同步校正仪的航空样机,它是一种多光谱偏振探测设备。利用该仪器可获取多光谱偏振信息,从而反演出与遥感成像时空同步的大气参数,实现大气校正。该仪器的定标处理对于准确获取大气参数至关重要。针对大气校正仪多通道偏振探测的特点,设计了定标方案。通过光谱定标、辐射定标和偏振定标,获取探测系统的Muller矩阵,建立仪器各通道探测值DN与斯托克斯参量间的联系,从而为系统的实际应用,提供重要基础。

Abstract:

Polarization detection system calibration presents great significance for atmospheric detection, and it is a necessary basis for high accuracy retrieval for atmospheric parameters based on polarimetric detection. A prototype of spaceborne atmospheric synchronous correction device was developed by  Anhui Institute of Optics and Fine Mechanics(AIOFM), which is a kind of multi-spectral polarimetric detection device. With this instrument, multi-spectral polarization information was obtained, and the atmospheric parameters synchronized with remote sensing image by time and space was retrieved. The calibration processing for the device is essential to acquire accurate atmospheric parameters. According to the multi-channel polarization detection features of atmospheric correction device, the system calibration was designed operated. By spectral, radiometric and polarization calibration, obtaining the Muller matrix of detection systems were obtained, therefore the relationship between detected values of each channel DN and the Stokes parameters was established, which provided an important basis for the practical application of the device.

Key words: polarization, multi-spectral, atmospheric detection, calibration
