How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Surface soil moisture has a wide application in climate change, agronomy, water resources, and in many other domain of science and engineering. Measurement of soil moisture at high spatial and temporal resolution at regional and global scale is needed for the prediction of flood, drought, planning and management of agricultural productivity to ensu...
Here we study the effect of soil texture, incidence angle and soil moisture content on the penetration depth of microwave pulses into the ground. In doing so, we have compared the penetration depth of SAR signals in soil using the Dobson empirical, Dobson semi-empirical and Hallikainen empirical model over samples collected at three different locat...
Microwave remote sensing has emerged as an efficient tool for the estimation of soil moisture due to its higher sen-sitivity to the dielectric properties of soil. Synthetic Aperture Radar (SAR) sensors have been used to estimate soil moisture at large scale. The penetration depth of microwave signals into the ground soil vary significantly with the...
We study the functional relationship between the dielectric constant of soil-water mixture and penetration depth of microwave signals into the ground at different frequency (L&S) band and incidence angles. Penetration depth of microwave signals into the ground depends on the incidence angle and wavelength of radar pulses and also on the soil proper...
