Spectral resolution and spatial resolution are two of the mutual restraint issues over hyperspectral imaging, which means that the spatial resolution usually gets worse as the spectral resolution increases. Two aspects of tilting mode imaging mechanism and super-resolution reconstruction of tilting mode imaging will be studied in this project, to improve the spatial resolution of hyperspectral images. The major contents of this project are as follows: 1) Spatial correction method for tilting mode imaging will be proposed while spectral consistency and spectral continuity will be considered for hyperspectral images. The intrinsic relationship between spatial resolution improvement，aliasing, blurring, noise will be analyzed,the mathmatic models of aliasing, blurring and noise will be given.2) The causes creating aliasing, blurring and noise for tilting mode imaging will be analyzed, the aliasing-removal, blurring-removal and noise-removal methods for tilting mode imaging will be proposed using converse-solving strategy, and then a super-resolution reconstruction method based on the tilting mode imaging and spatial distribution constraints will be proposed. 3) An earth observation model of tilting mode imaging will discussed for hyperspectral super-resolution reconstruction, and its test methods in practical application will be proposed. a prototype of super-resolution reconstruction of tilting mode hyperspectral imaging will be developed.. A novel way will be provided in this project to improve the quality and quantitative analysis of hyperspectral images.
