| Abstract: | Complex
permittivity (e’, e”) of sandy loam soil was measured in the frequency range 300 KHz -
1.5 GHz (using a vector network analyzer) and at 5.65 GHz (using microwave
bench set up) for various moisture contents in the soil. Measurements for
complex permittivity in this frequency range were also carried out for various
salinity levels of water content in the soil. The emissivity of the soil for
normal incidence was calculated from the measured value of complex permittivity.
It has been observed that at a given microwave frequency, emissivity decreases
with increase in moisture content in the soil. Further, the emissivity of the wet
soil, above transition moisture, decreases with increase in salinity level in
soil. The experimental data of complex permittivity and emissivity in this frequency
range can be useful in detecting the salinity and moisture content in the soil. |
