| dc.description.abstract | Dielectric
constant (ε′) and dielectric loss (ε′′) of artificially moistened soil
of Alwar have been determined at microwave frequency 9.78 GHz and at
temperature 32.5°C using wave guide cell method. In view of the active and
passive microwave remote sensing, the horizontal-horizontal radar
backscattering coefficient ( ) for bare and vegetative soil surface have been estimated by
Integral Equation Model (IEM) and Water Cloud Model (WCM), respectively using ε′
and ε′′ of soil and view angle as input parameters. The horizontal component of
microwave emissivity (eh) for bare soil surfaces have been
determined by emissivity model. The eh for
vegetative soil surfaces determined by radiative transfer equation using
suitable vegetation dependent parameters, like single way vegetation transmissivity and single scattering
albedo (ω) for agricultural vegetation, respectively. The present study reveals
that the for
bare and vegetative soil surface exhibit a positive correlation with
soil moisture content (SMC).
Vegetative soil surface is lower than that of bare soil surface for
the same values of SMC and view angle. Further, eh for bare and vegetative soil surfaces
decreases with an increase in SMC. Vegetative soil surface emissivity is higher
than that of bare surface for the same values of SMC and observation angle.
Further, backscattering coefficient and emissivity for bare and
vegetative soil surfaces decrease as the angle of observation increases due to
contribution of diminished coherent component.
