摘　　要：由于红外干涉成像光谱仪结构的特殊性,其非均匀性在线定标与校正是工程上一直没有得到有效解决的技术难题。通过对光谱仪结构的深入分析,对空间调制红外干涉光谱仪研究出了一种有效的非均匀性在线定标与校正方法,并建立了相应的仿真模型,实验结果表明算法是正确的和有效的。研究成果为星载空间调制红外干涉成像光谱仪非均匀性的在轨定标与校正奠定了良好的技术基础。Due to the particular structure of interference infrared imaging spectrometer, its online nonunfformity calibration and correction is always a difficult technical problem which has not been solved in engineering. Based on the in-depth analysis of principle and structure to the space- modulated interference infrared imaging spectrometer, an effective method of online nonuniformity calibration and correction was developed for this type spectrometer. The corresponding simulation model for the algorithm was given. The simulation results had shown the correctness and validity of the algorithm, which should make it possible for the on-orbit nonuniformity calibration and correction of spaceborne interference infrared imaging spectrometer.
