抽象的。用于大气辐射成像的万向节肢观测器（格洛丽亚）是一种成像傅里叶变换光谱仪，能够在各种高空研究飞机上运行。它在临边和天底几何学中测量热红外光谱区的大气发射。格洛丽亚由一个经典的迈克尔逊干涉仪和一个红外相机组成。红外探测器的可用面积为128 × 128像素，可同时测量多达16384幅干涉图。成像傅里叶变换光谱仪在仪器校准和算法开发方面提出了许多挑战。具有极高光通量的光学设置需要开发用于光谱和辐射校准的新方法和算法。由于数据量巨大，因此对数据处理的科学智能优化有很高的需求。本文概述了产生辐射和光谱校准光谱所需的表征和处理步骤。处理算法的性能优化的方法。的数据处理的性能和校准光谱的质量证明了在第一次部署的格洛丽亚飞机上收集的测量。
Abstract. The Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA) is an imaging Fourier transform spectrometer that is capable of operating on various high-altitude research aircraft. It measures the atmospheric emission in the thermal infrared spectral region in limb and nadir geometry. GLORIA consists of a classical Michelson interferometer combined with an infrared camera. The infrared detector has a usable area of 128 × 128 pixels, measuring up to 16 384 interferograms simultaneously. Imaging Fourier transform spectrometers impose a number of challenges with respect to instrument calibration and algorithm development. The optical setup with extremely high optical throughput requires the development of new methods and algorithms for spectral and radiometric calibration. Due to the vast amount of data there is a high demand for scientifically intelligent optimisation of the data processing. This paper outlines the characterisation and processing steps required for the generation of radiometrically and spectrally calibrated spectra. Methods for performance optimisation of the processing algorithm are presented. The performance of the data processing and the quality of the calibrated spectra are demonstrated for measurements collected during the first deployments of GLORIA on aircraft.
