5. CONCLUSIONS
In this paper, a new algorithm on SAR image ortho-rectification
has been proposed based on polynomial rectification and height
displacement correction, which was provided with a systematic
theory. It could be realized simply and rapidly, and it was very
superior to other algorithms without precise catalogue data.
From the analysis and the comparison to some experiments with
space borne (ERS-2 and Radarsat) and high resolution airborne
SAR images, it is shown that this new algorithm reached
satisfying results in mountain area.
