Investigation on Vegetation Height Retrieval Technique with Compact PolInSAR Data

A three-stage vegetation height inversion method with compact polarimetric SAR interferometric data is proposed. The coherence optimization method applied to full PolInSAR data processing is introduced into compact PolInSAR processing. The optimum phase is used to get the initial estimation of volume decorrelation and ground phase. Volume decorrelation estimation is updated with coherence boundary extraction method. Simulated L-band full PolInSAR data provided by ESA is used to construct compact PolInSAR data, and the generated data is used for vegetation height inversion. Inversion results confirm the validity of the proposed method.
