Drone-Borne Ground-Penetrating Radar for Snow Cover Mapping

open access: yesRemote Sensing, 2022
Ground-penetrating radar (GPR) is one of the most commonly used instruments to map the Snow Water Equivalent (SWE) in mountainous regions. However, some areas may be difficult or dangerous to access; besides, some surveys can be quite time-consuming.

Effect of Radar Incident Angle on Full-Wave Inversion for the Retrieval of Medium Surface Permittivity for Drone-Borne Applications

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Drone-borne ground-penetrating radar (GPR) has proven to be efficient and promising for high-resolution topsoil moisture mapping at the field scale. However, in practice, the radar incident angle may change as a function of the terrain slope as well as unstable flying conditions.

Drone-borne Differential SAR Interferometry

open access: yesRemote Sensing, 2020
Differential synthetic aperture radar interferometry (DInSAR) has been widely applied since the pioneering space-borne experiment in 1989, and subsequently with the launch of the ERS-1 program in 1992. The DInSAR technique is well assessed in the case of
