Inversion of Vegetation Parameters Using Spaceborne Polarimetric SAR Interferometry
|
Abstract:
Based on the basic principal of ploarimetric SAR interferometry(Pol-InSAR)and coherent scattering model, the inversion algorithm of vegetation parameters based on Simulated Annealing Algorithm is presented. First, the basic principal of Pol-InSAR and the two-layer coherent scattering model taken into account the scattering of surface and vegetation are discussed. Then, the basic theory of Simulated Annealing Algorithm and the inversion model based on Simulated Melt-Annealing Algorithm are discussed. At last, utilizing the complex single Sinclar matrix data of spaceborne SIR-C L-band , on October 9 and 10, 1994, the inversion of vegetation parameters is implemented. Comparison of the result of inversion with field measurement data indicates that the inversion algorithm can obtain the height of vegetation with good accuracy .
