Abstract
We have conducted a feasibility study on measuring the tree height distribution by using polarimetric SAR interferometry datasets acquired by the NASDA-CRL's L-band Polarimetric Interferometric Synthetic Aperture Radar (PI-SAR). Test site is the Tottori Dune and its surrounding area, where pine trees were planted. Coherence and the phase differences obtained by the interferometric analysis were evaluated. As a result, we could estimate the tree height distribution if the polarimetric SAR images (co-pol and cross-pol) are acquired with larger baselines and smaller slant ranges. Quantitative evaluation is required to relate the phase center differences and the tree types and the polarization combinations.
