Remote Sensing of Soils, Minerals, and Geomorphology:
GPR (Ground Penetrating Radar): The radar transmits high frequency, short
duration pulses of energy into the ground from a coupled antenna. Transient
electromagnetic waves are reflected, refracted, and diffracted in the subsurface by
changes in electrical conductivity and dielectric properties. Travel times of reflected,
refracted and diffracted waves are analyzed to give depths, geometry and material type
information
