Non-linearity of Soil Dielectric Constant as a Function of Radar Frequency and Soil Moisture Content
Soil is a mixture of four components: air, free water, bound water and soil particles. The microwave dielectric constant of soil is strongly dependent on the soil moisture content. The dielectric constant is a measure of the response of a material to an applied electric field, such as an electromagnetic wave. It has a real and an imaginary component. Soil particles’ dielectric constant depends ...
متن کاملIn-Situ Measurement of Soil Permittivity at Various Depths for the Calibration and Validation of Low-Frequency SAR Soil Moisture Models by Using GPR
At radar frequencies below 2 GHz, the mismatch between the 5 to 15 cm sensing depth of classical time domain reflectometry (TDR) probe soil moisture measurements and the radar penetration depth can easily lead to unreliable in situ data. Accurate quantitative measurements of soil water contents at various depths by classical methods are cumbersome and usually highly invasive. We propose an impr...
متن کاملValidation of ground penetrating radar full-waveform inversion for field scale soil moisture mapping
Ground penetrating radar (GPR) is an efficient method for soil moisture mapping at the field scale, bridging the scale gap between small-scale invasive sensors and large-scale remote sensing instruments. Nevertheless, commonly-used GPR approaches for soil moisture characterization suffer from several limitations and the determination of the uncertainties in GPR soil moisture sensing has been po...
متن کاملFrequency Domain Gpr Signal Forward and Inverse Modelling for Identifying the Subsurface Dielectric Properties
Research has focused on the development of a new integrated approach including ground penetrating radar (GPR) design, GPR signal forward modelling, and GPR signal inversion to estimate the dielectric permittivity and electric conductivity of the shallow subsurface. We propose to use an ultrawide band (UWB) stepped frequency continuous wave (SFCW) radar combined with an offground monostatic tran...
متن کاملTemporal Monitoring of the Soil Freeze-Thaw Cycles over a Snow-Covered Surface by Using Air-Launched Ground-Penetrating Radar
We tested an off-ground ground-penetrating radar (GPR) system at a fixed location over a bare agricultural field to monitor the soil freeze-thaw cycles over a snow-covered surface. The GPR system consisted of a monostatic horn antenna combined with a vector network analyzer, providing an ultra-wideband stepped-frequency continuous-wave radar. An antenna calibration experiment was performed to f...
