Abstract :
The materials presented below concern the questions of utilization of airborne SAR operating at four frequencies (4, 23, 68 and 254 cm). Results of algorithms for inverse problem solution (which is incorrect) development are presented. These problems are the moisture profile determination, detection of subsurface cracks, splits, cavities and so on using the results of radar mapping at different wavelength ranges. The outputs were approbated to explain the results of radar sensing in the regions of desert with water lenses.
