Abstract
Polarimetric interferometric SAR (PolInSAR) is a new advanced technique based on measurement techniques of polarimetric SAR and interferometric SAR, and making use of it for retrieving the vegetation parameters becomes a hot research topic at present. In this paper, a high precise vegetation height estimation method is presented using dual frequency PolInSAR data. This method is based on fusion of dual frequency differencing and the coherence amplitude method. It can not only keep the accuracy of vegetation height estimation, but also it reduces the calculation of the algorithm greatly. Finally, the simulated PolInSAR data are used to validate the proposed method.
