P. Ferrazzoli et al., THE POTENTIAL OF MULTIFREQUENCY POLARIMETRIC SAR IN ASSESSING AGRICULTURAL AND ARBOREOUS BIOMASS, IEEE transactions on geoscience and remote sensing, 35(1), 1997, pp. 5-17
Polarimetric radar data collected by AIRSAR and SIR-C over agricultura
l fields, forests, and olive groves of the Italian Montespertoli site
are analyzed. The objective is to investigate the radar capability in
discriminating among various vegetation species and its sensitivity to
agricultural and arboreous biomass. Results indicate that a combined
use of P (0.45 GHz) and L (1.2 GHz) bands allows one to discriminate b
etween agricultural fields and other targets, while a combined use of
L and C (5.3 GHz) bands allows us to discriminate within agricultural
areas, To monitor biomass, P band gives the best results for forests a
nd olive groves, L band appears to be good for crops with low plant de
nsity (m(-2)), while for crops with high plant density, both L and C b
ands are useful, The availability of crosspolarized data is important
for both classification and biomass retrieval.
