P. Ferrazzoli et al., MODELING X-BAND AND KA-BAND EMISSION FROM LEAFY VEGETATION, Journal of electromagnetic waves and applications, 9(3), 1995, pp. 393-406
Emissivity of agricultural crops is theoretically estimated through a
model based on the Radiative Transfer Theory, and then compared with e
xperimental data collected at X and Ka bands. The test is in general p
ositive. The model and the experimental data agree in showing the abil
ity of a dual-frequency radiometer system to discriminate different fi
eld types. The importance of a realistic choice of the dimensions, ori
entation and relative position of the scattering elements within a veg
etation layer is pointed out.
