The mathematical description of the rise of radio-brightness contrasts (RBC) of terrains with the chaotic roughnesses and local dielectric anomalies is offered with account of scattered thermal radiation of atmosphere. The analysis of influence of humidity, porosity, as well as terrain roughnesses on radio-brightness contrasts was carried out. In natural conditions at wavelength of 8 (DOT) 10-3 m the measurements of RBC--wet/dry ground, dense/loose soil, metal/ground were performed. The comparison between experimental data and theory have shown its good agreement, that testifies about adequacy of offered mathematical description. The technique and results of stochastic synthesis of radio-thermal images of the wood, sandy bank, river and island from aerial photos and corresponding trace radiometric measurements are submitted. The reliability of synthesis is confirmed by correlation overlapping of the synthesizing radio-image and fragment of radiometric profile, which was not used in the synthesis.
