英文摘要	Based on the principle of ALOS PRISM, a rigorous geometric model is established by imagery ancillary data. This progress can be seen as a series of coordinate system transformation. Then we use the rigorous geometric model to achieve for georeferencing of ALOS/PRISM imagery. Experimental results show that there would be constant systematic errors existed in side watch angle. In order to eliminate the systematic error, a new matrix was introduced. It is used to rectify the look direction in ECR coordinates. Once the systematic errors are eliminated, the result is improved noticeably. Accuracy is better than 5 m for the planar position and 3 m for the altitude. It shows that the improved rigorous geometric model is very stable and the accuracy of direct georeferencing is also very ideal. However, in different areas, the accuracy is a little different. The result shows that the change of side watch angle may act on the final orientation accuracy.5.; EI; 0; 5; 569-574+581; 40
