Abstract

Abstract

A vegetation parameters inversion algorithm based on Oriented Volume (OV) model is presented for vegetation with polarization characteristics, and the model and the algorithm is verified with a hard-in-loop polarimetric SAR interferometriy system constructed in an anechoic chamber. According to the vegetation characteristics of OV model, the difference of co-polarization represented dihedral scattering mechanism is discriminated as a basis for topographic phase, finally the retrieval vegetation height is gained by calculating the average and standard deviation. Next, a hard-in-loop broadband polarimetric SAR interferometric system is constructed in a controlled environment. The baseline is calibrated by two trihedral angles with height known. The experimental results show that the retrieval height is fluctuated 0.03 m to the actual height, and the inversion error is less than 0.2 m in the whole band, which explain the feasibility of model and the inversion algorithm.
