  • 摘要:This paper introduces an ortho-rectification method of airborne SAR images which is multi-photo combined adjustment method based on F.Leberl imaging model. Multi-photo combined adjustment model of airborne SAR images is built. Multi-photo combined adjustment conditions are given in this paper. This method is applicable to multi-temporal, multi-side-looking-orientation, multi- flight-height, multi-resolution SAR Images. Two adjustment experiments have been done with one-meter resolution airborne SAR images in Chengdu study site. In the two experiments, the GCPs and the Pass Points are distributed rationally in each image. The two experimental results show that the coordinate accuracy of Pass Points is feasible for 1:10 000 scale ortho-image making and topographic map updating. There are four images in the first experiment, and nine GCPs and ten Pass Points are used. There are eleven images in the second experiment, and nine GCPs and thirty Pass Points are used. The second experimental result is better than the first one. Because the Pass Points are twice overlap in the first experiment and the most Pass Points are more than twice overlap in the second one
