Presently the development of researches on the calibration of Pol-InSAR at the stage of the theory and test. There are many limits in the current algorithm. A new improved algorithm is set up with using the sensitivity equation based on the analysis of the errors source. The algorithm get the parameter value by the iterative method based on the sensitivity equation. The algorithm not only improves the precision but also overcome the flaw of homogeneous flat model, reducing the limit condition. By the simulation experiments, it has been proved that the performances of the new improved algorithm is better than the conventional algorithm.
