讨论了海洋在微波频率下的表观温度，提出了一种基于基尔霍夫近似的理论，从粗糙的，粗糙的导电表面的散射。详细的数值结果的温度随风速的变化进行了讨论的频率为19.4 GHz。海洋均方根斜率对风速的依赖性是基于实验测量的，这在理论上是需要的。结果发现，显着的温度变化发生随着风速的水平偏振辐射。垂直偏振辐射的温度受风的影响要小得多，在50度角（19.4 GHz）时，几乎与海洋状态无关。
A discussion of the apparent temperature of the sea at microwave frequencies is presented using a theory based on the Kirchhoff approximation for scattering from rough, finitely conducting surfaces. Detailed numerical results on the variation of the temperature with wind speed are discussed for a frequency of 19.4 GHz. The dependence of the rms slope of the sea on wind speed, which is needed in the theory, is based on experimental measurements. It is found that significant temperature changes occur with increasing wind speed for horizontally polarized radiation. The temperature of vertically polarized radiation is much less affected by the wind and, at an angle of 50\deg (at 19.4 GHz), is almost independent of the state of the sea.
