Description
technical field [0001] The invention belongs to the technical field of spectral imaging remote sensing analysis, in particular to a chip-level spaceborne hyperspectral imaging detector and a spectral imaging method thereof. Background technique [0002] Spectral information has fingerprint characteristics, and remote sensing spectral analysis technology is based on the target spectral characteristics of the wavelength and reflection intensity produced by the interaction between electromagnetic radiation and matter. Spectral feature extraction can directly reflect the spectral absorption and reflection characteristics of the target. In the determined characteristic spectral position, it can accurately calculate the reflectivity, spectral absorption index and other indicators, and perform accurate and comprehensive quantitative analysis on the spectral characteristics of specific targets. On the basis of remote sensing image information, hyperspectral information is further ob...
