The field programmable gate array is adopted as a core controller, the infrared detector and the visible light detector are adopted to form two imaging channels, multiple imaging functions can be achieved, and the multi-mode multi-spectrum integrated space remote sensing imaging unit has the advantages of being low in cost, high in integration level, high in processing capacity, good in expandability and the like.

Description

technical field [0001] The invention relates to the technical field of aerospace remote sensing load imaging, in particular to a multi-mode and multi-spectral integrated load imaging unit. Background technique [0002] Aerospace optical remote sensing technology refers to the use of optical cameras to observe ground targets from low-Earth orbit to obtain relevant information. According to the observation spectrum, aerospace optical remote sensing technology is divided into three categories: ultraviolet remote sensing, visible light remote sensing and infrared remote sensing. The current aerospace optical remote sensing technology usually uses visible light remote sensing and infrared remote sensing for earth observation. [0003] Visible light remote sensing has basically the same spectral band as human visual observation, and can obtain intuitive target information, but it is easily interfered by factors such as lighting conditions, cloud and fog occlusion, and can only be ...
