The science of microwaves owes its origin to the development of radar. Microwaves are part of electromagnetic spectrum. This field became vitally important as man reached out to space. Frequency range of these waves are from 3 GHz to 30 GHz. Microwaves have unique capabilities in remote sensing. The field of microwaves remote sensing has come to a stage of(More)
The emission from the vegetation canopy depends on the type of vegetation and the frequencies at which the emission is measured. For studying the vegetation canopy of a tree, the dielectric constant of its constituent is measured at microwave frequencies. In this study the dielectric constant is measured using waveguide cell method and its scattering(More)
The rocks are formed during the process of formation of earthpsilas crust. Rocks found on the earth surface are mainly three types, namely, igneous, metamorphic and sedimentary rocks. The microwave link operating over the rocky surface results in the fading of the received signal. The effect of rocky terrain on microwave link is manifested in the fading of(More)
The soil is one of the natural earth material which is produced by withering of rocks. The soil is characterized by its physical and electrical parameters. The physical parameters include the texture, temperature, surface roughness. The electrical parameters are dielectric constant, emissivity and scattering coefficient. The emissivity and scattering(More)
