摘要
A methodology for calibration of Synthetic Aperture Radar (SAR) images is given based on combining first and second order statistics from ocean images. It is shown to be, compatible with transponders in accuracy, easy to use, and low cost operational. ERS-1 and ERS-2 data are used in this study to demonstrate the performance and potential of the methodology. An accuracy of 0.47dB is obtained from using only one ERS-2 image. Improvements of accuracy can be obtained by using several independent images. The method can be used to monitor and update the absolute calibration constant of spaceborne SAR images.
