Abstract

This paper describes an efficient 3-D positioning method of SAR image only using ephemeris data and a single control point. The proposed method is applied to RADARSAT-1 SGF images of which ephemeris information is not accurate enough to directly use for the dynamic geometric modeling. The RMSE of the 3-D model by using a single CP (Control Point) is 43.86m, while that of traditional method using 10 CPs is 45.79m in comparison with reference 3-D model generated from 1:5,000 digital topographic maps of the study area. The test results show that even without the use of many CPs, it is possible to generate similar accuracy of 3D-model comparable to traditional method.
