Paper Abstract

SAR can be used in topographic mapping at any time with all weather situations. In order to realize accurate surveying and mapping with SAR, a positioning scheme of airborne stereo SAR images with POS and one GCP (Ground Control Point) is proposed. In this scheme, the instantaneous position and velocity of antenna are obtained from the POS data, the close range and the Doppler center frequency are calibrated with only one GCP so as to realize accurate positioning of airborne stereo SAR images. The stereo SAR images obtained by Chinese airborne SAR system were utilized in positioning experiments. The errors of positioning were calculated and analyzed. The results demonstrated that the proposed scheme is valid.
