Abstract :
For the first time, the geometrical characteristics (depth and size) and the temperature of a local thermal volume located in a homogeneous lossy material can be deduced from radiometric data. An example devoted to physical models (the lossy material is water) is based on the processing of radiometric data at 1.5 and 3 GHz.
