Simulation Process For Circular Scanning Imaging A Real Scene Image Compared with traditional push broom imaging, the space camera that performs the new circular scanning imaging can effectively enlarge the imaging area and obtain high resolution images. however, the imaging velocity fields of space camera will seriously deteriorate the image quality in the circular scanning imaging process. and the velocity fields are anisotropically distributed due to. In 2020, xu [21] et al. studied velocity vector on the image surface of a space camera for dynamic circular scanning, and carried out numerical and image simulation. in the same year, based on. A mathematical model of the velocity field is proposed to analyze the effect of circular scanning imaging and provides guidance for attitude planning and imaging assessment for new remote sensing imaging of space cameras. compared with traditional push broom imaging, the space camera that performs the new circular scanning imaging can effectively enlarge the imaging area and obtain high. Therefore, the factors affecting the imaging quality of the imaging link in the large field circular scanning system can be summarized as the imaging blur, the coupling process of the detector rotating sampling and the satellite vibration, the photoelectric conversion process and the random noise.

Drift angle analysis for agile satellite imaging when its attitude points to the earth changing continuously. drift angle exists in dynamic imaging for an agile satellite in three axis attitude maneuvering,e.g.the direction of image acquisition is not parallel with the satellite platform motion.based on…. The whiskbroom scanning imaging mode effectively expands the imaging field of the space optical camera, and realizes high resolution and wide width spatial imaging. however, the dynamic disturbance in the short term and large scale imaging process will cause uneven degradation of the image. therefore, a geometric model of the camera instantaneous imaging at a moment is constructed. then, the.
