Development Analysis of Foreign Hyperspectral Remote Sensing Loads

Hyperspectral remote sensing is the frontier field of current remote sensing. Firstly, the basic theory of imaging principle, typical imaging mode and main features of hyperspectral remote sensing are introduced. Then, from the aspects of airborne and spaceborne, the development of hyperspectral remote sensor in major countries, such as United States, Canada, Europe and Japan is summarized, and the main performance indicators of the relevant sensors, including spatial resolution and spectral resolution as the main ones, are analyzed. With the summary and induction of the application of hyperspectral remote sensing in the three fields of civil and commercial, national defense and planetary detection, this article finally summarize the development trend of hyperspectral remote sensor from the following aspects as improving resolution, optimizing detection mode and miniaturization.
