摘要
在空间遥感中为了降低由仪器的偏振敏感性引起的误差,常用的方法是采用退偏器和在轨偏振修正。介绍了在轨偏振修正的理论,在此基础上推导了偏振修正所需的仪器缪勒矩阵元素的一种标定方法超定方程法,并利用该方法计算出紫外臭氧垂直探测仪的缪勒矩阵元素,对测量结果进行了误差分析及验证,结果表明了该方法的可行性及精度。
Errors caused by polarization sensitivity of remote sensing spectrometer must be reduced to meet the requirements of the reliability and precision of remote sensing data. The common method is the use of the depolarization and in-orbit polarization correction. This polarization correction method is introduced in theory. The overdetermined equation, calibration formula of Mueller matrix elements required is deduced. By this formula, the Mueller matrix elements of ultraviolet ozone vertical profile probe are calculated. In combination with the results, the errors by the method are analysed and feasibility as well as precision is also validated.
