According to the gap in the field,the effect of mutative skin temperature on objects' millimeter wave radiation temperature is studied. The radiation temperatures of various objects with different skin temperatures are measured by 3 mm DC Dicke radiometer.The result shows the change rules of radiation temperatures of objects with different emissivities are distinct.And the effect is more obvious as the higher emissivity.Based on measured data, temperature variation coefficients of various objects are calculated by the least square method.

针对目标表面温度实时变化引起毫米波辐射变化的规律尚未被研究的现状，使用3 mm直流Dicke式辐射计对不同表面温度条件下的目标辐射温度进行了测量，发现使用不同发射率材料的目标的辐射温度随表面温度变化的规律明显不同，材料发射率越高，目标辐射温度受表面温度的影响越大。
