In the nigh-resolution satelliteborne remote sensing TDICCD camera, angular velocity of the image is changed with variation of the velocity-height ratio ( v/H) of the satellite, and the image quality of camera is deteriorated seriously. Thus, the variation rule of the v/H was studied at the imaging of satelliteborne TDICCD camera. Influence of v/H on the image quality was studied from two variations oi imaged ground scenery latitude and IDICCD camera scroll angle . The interval of reg?ulation of the row integration time and the range of the scroll angle at the imaging were computed based on the given oroital parameters. The effect of the field of view on the image quality was finally- analyzed .
