Abstract
We depict a method of determination of the size D depth z and temperat ure T0 + DELTAT of a cylindrical thermal structure embedded in an homo geneous lossy material, in the present case, water. A microwave radiom etric image at 3 GHz points out the location of the thermal structure; its threshold provides the diameter D of the structure. The depth z d erives from the ratio of the maximal-radiometric intensities at 1.5 an d 3 GHz. The combination of D, z and of the radiometric intensities gi ves DELTAT.
