摘要：
The sensitivity to herbaceous and arboreous vegetation biomass of backscattering coefficient measured by ERS-1 and JERS-1 radars is discussed and compared with the best results achieved using the multi-frequency polarimetric AIRSAR data. Experimental results obtained on Montespertoli test site show that, measurements with JERS-1 L-band SAR (theta = 35 degrees incidence angle) are able to detect vegetation growth, while, at the observing parameters of ERS-1 SAR (C-band, theta = 23 degrees), the relation between backscattering and vegetation biomass is more complicated and depends on crop type and appears significantly affected by soil moisture.
