Description
Summary:碩士 === 國立中央大學 === 土木工程研究所 === 87 === This paper begins with elaborating the deduction and solutions of Radargrammetric Condition Equations on a single SAR (Synthetic Aperture Radar) image, which is the time-varying SAR airborne flight locus represented with polynomial collaborating with the mixed adjustment method. As for the blunder detection in observation data, in order to apply τ-test in detecting the possible blunder in observation data to assure its quality, the orientation parameter used to be described with two-order polynomial in previous researches. In this paper, one appropriate high-order polynomial is chosen in the first place to proceed with the optimization of the orientation parameter originally presented by two-order polynomial. The result of the experiment has shown that the check point precision is 4.5-5.5 meter horizontally and 5.0 meter vertically, which proves to be better than two-order polynomial. This is going to make positive contributions toward the precision promotion in the subsequent researches on geocoding of SAR image. The experimental area located near the Yang-mei town, Taoyuan County is 12 km from east to west and 9 km from north to south with the largest height difference about 150 m.
