Pulse Electromagnetic Sounding of the Permafrost Layered Medium
In this paper, the reflection of a super wide-band electromagnetic pulse from an active layer of permafrost is theoretically modeled. The dielectric model applied for such a frequency dispersive medium takes into account in thawed and frozen soil the contributions from the organic/mineral fraction of the soil, liquid soil water, bound soil water, and ice particles. The numerical algorithm developed allows to model the amplitude of the GPR pulse, which finally makes possible to simulate GPR images of a layered permafrost medium in the course of its freezing and thawing. The impact of a frozen/thawed boundaries inside the layer on the reflected pulse form were studied. The dynamic range of the GPR allowing to monitor the depth of thawed layer is evaluated.
