The Influence of Elevation on the TDICCD Camera's Image Motion Compensation

The High-resolution remote sensing satellites often use TDICCD cameras, and the satellites should use the image motion compensation technology in the imaging process in order to acquire high-quality images. But now most technologies ignored the impact of the elevation. On the basic of imaging vector model under the ellipsoidal earth model, this paper built the vector model and the calculation flow that considered the earth elevation. According to the results, this paper analyzed the effects of elevation on the image motion compensation parameters. Then the paper discussed the production of the Space-borne DEM by synthetically considering the restriction of the elevation error, space-borne storage space and query speed. The use of Space-borne DEM will provide the theoretical basis and the experimental analysis for the high accuracy image motion compensation.
