The model-based polarimetric interferometric synthetic aperture radar forest height inversion is inherently affected by nonideal system parameters, including channel imbalance, crosstalk, and noise. To investigate the impact of nonideal system parame

At present, the principal data processing methods involving complex observations are based on two strategies according to characteristics of the observation process, i.e., step-by-step and direct resolution. However, these strategies have some limita

In this paper, we introduce a refined three-stage inversion algorithm (TSIA) for forest height estimation using polarimetric interferometric synthetic aperture radar (PolInSAR). Specifically, the iterative extraction of the boundary of the coherence
