Abstract

Two SAR tomographic estimators, namely the Capon method and the MUSIC method, are combined for the purposes of tree top height estimation and ground elevation retrieval from the dual-baseline datasets acquired by an experimental single-pass fully polarimetric L-Band InSAR system. Over two test sites, the preliminary results demonstrate a better estimation performance than our previously published results [4,5] using established single-baseline PolInSAR retrieval approaches.
