Study Proposes Real-Time Permittivity Estimation Method for Stepped-Frequency Ground-Penetrating Radar

Ground-penetrating radar (GPR) has long been a pivotal tool in estimating the permittivity of various mediums. A significant technique used in this estimation is the radar echo amplitude method, which crucially derives permittivity magnitude through the correlation between reflection coefficients and permittivity. Building upon this principle, a recent study published in Remote Sensing on Oct. 31 introduces a full-wave inversion real-time permittivity estimation method specifically tailored for stepped-frequency GPR (SFGPR).
