The analysis of polarimetric InSAR system key parameters based on vegetation estimation

Polarimetric synthetic aperture radar(SAR) interferometry is a new technology that fuses the polarimetric information and interferometric information of the landscape together. In recent years, vegetation height estimation is becoming one of most successful applied technology of polarimetric InSAR. With this applied technology, we can better understand the polarimetric scattering mechanisms and decompose the backscatter return from different levels in vertical structure of vegetation and measure trees height. Several key parameters of polarimetric InSAR system are studied and analyzed to find the optimized parameters of polarimetric InSAR system based on vegetation height estimation technology in this paper. Two emulator arithmetics will be studied to apply experimental data for different purposes in our experiments. Actually both of the arithmetic have their own disadvantage and advantage each other. The experiment results have shown that it´s really meaningful to analyze and find optical parameters of polarimetric InSAR system based on vegetation height estimation.
