Abstract
In this paper, results of GPR experiments carried out in Nalaih, Mongolia and Yakutsk, Russia will be shown. In the measurements, target is ground water and permafrost. Especially in these regions, there are special kind of permafrost structure, which are important in the study of permafrost. In Nalaih, there is 'pingo,' which is composed of several layers including permafrost in the subsurface. We applied Common Midpoint method to estimate vertical profiles. In analysis of the CMP data, we applied f - k filtering and NMO correction, which are common techniques in seismic signal processing. In our GPR data, there are reflected waves from the permafrost surface and we accurately estimated the structure of the permafrost of the pingo. In Yakutsk, Russia, there are also special structures at a few meter depth in Taiga region. We will show experiment results of GPR at the field, and we will interpret the data to detect the structure with GPR. Also we tried to compare GPR data and SAR data in Nalaih, Mongolia, and we considered interpretation of SAR.
