ABSTRACT
We depict a method of determination of the size D depth z and temperature T0 + delta T of a cylindrical thermal structure embedded in an homogeneous glossy material, in the present case, water. A microwave radiometric image at 3 GHz points out the location of the thermal structure; its threshold provides the diameter D of the structure. The depth z derives from the ratio of the maximal radiometric intensities at 1.5 and 3 GHz. The combination of D,z and of the radiometric intensities gives delta T.
