Applications of high-frequency GPR to investigating permafrost-affected soils of peat plateaus have been analyzed. To assess the technical capabilities of high-frequency antennas, the depth of both permafrost table and lithological contacts at virgin (peat mounds and fens) and anthropogenically transformed (zone of defrosting influence of the cement-concrete road) sites of peat plateaus have been determined. The 300 and 900 MHz-frequency surface shielded antennas were used simultaneously in the conditions of considerable variability of the depth of permafrost table and mineral horizons bedding in the upper 10-meter soil strata. Application of the shielded air-coupled 1000 and 2000 MHz antennas to determining the permafrost table depth has been additionally assessed.
