A new method for calibration of SAR image

With the rapid development of remote sensing technology in these years, people can get a lot of synthetic aperture radar (SAR) images of the earth´s surface easily. The problem is that, people need to know the exact properties of the ground surface from the SAR images which is derived from the different kinds of remote sensing system. So the calibration of SAR image is needed. In this paper, a new methodology for calibration of SAR images and its realization for existing airborne strip map SAR system are put forward. After analysis of the range-Doppler imaging algorithm, a system model is given, and a calibration method is proposed in this paper. Computer simulation is used to verify the validity of this calibration method.
