Description

technical field [0001] The invention relates to the technical field of imaging mode design and application of a remote sensing camera, in particular to an imaging system and method for realizing a wide-area search of a large field of view by using a camera with a small field of view. Background technique [0002] The quality, volume, resolution, and width of the imaging system of aerospace remote sensing cameras have always been mutually restricted. In the traditional design ideas of aerospace remote sensing cameras, in order to achieve high-resolution and wide-format imaging, the entire imaging system must The caliber, focal length and other indicators will inevitably increase significantly, which directly brings about the improvement of the quality and volume of the imaging system itself, which in turn leads to an increase in the volume of the remote sensing platform. In applications such as wide-area search, remote sensors are required to have a large field of view, and t...
