Abstract :
More and more people begin to realize the polarimetric calibration is important and necessary to the geophysical research and applications. In this paper, two kinds of polarimetric crosstalk calibration methods, including the one using only points target and the other one with distributed target, are compared and analyzed in details firstly. And then, an airborne polarimetric SAR data are applied to calibration with the methods by Quegan and Ainsworth. Finally, the experimental results and conclusions are also presented in this paper.
