The problem of the effect of apodization on the retrieval of geophysical parameters from infrared radiances recorded by Fourier transform spectrometers has been analytically and numerically addressed. Exploiting a matrix representation of apodization, we first derive a general analytical expression for the apodized covariance matrix and then show that apodization, when properly applied, has no effect on retrievals. The methodology has been applied to investigate the effect of Gaussian apodization on the Infrared Atmospheric Sounding Interferometer currently under development at the laboratories of the French Space Agency.
变迹对从傅里叶变换光谱仪记录的红外辐射中反演地球物理参数的影响问题已通过解析和数值方法进行了研究。利用变迹的矩阵表示，我们首先推导出变迹协方差矩阵的一般解析表达式，然后表明，当变迹得到恰当应用时，它对反演没有影响。该方法已被用于研究高斯变迹对法国航天局实验室目前正在研制的红外大气探测干涉仪的影响。
