Description

Technical field [0001] The invention relates to the technical field of imaging mode design and application of remote sensing cameras, in particular to an imaging system and method for realizing a wide-field search with a large field of view using a small field of view camera. Background technique [0002] The quality, volume, resolution and width of the imaging system of aerospace remote sensing cameras have always restricted each other. In the design of traditional aerospace remote sensing cameras, in order to achieve high resolution and wide imaging, the entire imaging system is Indicators such as aperture and focal length will inevitably increase significantly, which directly leads to an increase in 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 the manufacture of large-field cameras is o...
