The results of experiments performed in 2007–2009 in the centers of the developed permafrost regions of Yakutia in order to prove the hypotheses about the temperature field effect on the electromagnetic field attenuation in permafrost have been summarized. It has been demonstrated that this phenomenon exists and has region-specific patterns within the layer of annual temperature variation in the built-up areas with different conditions. The procedure of investigation of the temperature dependence and the mathematical modeling for estimating ground temperatures from the ground penetrating radar data has been described. The simulation error has been examined. Lines for further research have been identified, and recommendations on the practical use of models have been formulated.
