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.
我们描述了一种确定嵌入均匀光滑材料（在本案例中为水）中的圆柱形热结构的尺寸D、深度z和温度T0 + ΔT的方法。3GHz的微波辐射图像指出了热结构的位置；其阈值给出了结构的直径D。深度z由1.5GHz和3GHz处的最大辐射强度之比得出。D、z与辐射强度的组合得出ΔT。
