| Abstract: | Based on numerical difference between the first order and high order Mueller matrix solutions, an iterative method for inversion of surface moisture and fraction per unit area of random small spheroids from polarimetric backscattering measurement is developed. Using numerical simulation and measured AirSAR data of polarimetric Mueller matrix, the inversion of different surface moisture and fraction per unit area are studied. |
