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.
