Inversion of Forest Height Based on ALOS-2 PARSAR-2 Multi-baseline Polarimetric SAR Interferometry Data

Leida xuebao, 2020
To compensate for the limitations of insufficient observation information and simplistic geometric structure of single-baseline InSAR, this study proposes a new method for extracting forest height from ALOS-2 PARSAR-2 multi-baseline PolInSAR datas ...
