blackbody radiometer

基本解释

An intelligent calibration system with temperature of blackbody naturally varying used for small antenna MMW radiometer was developed.
研制了的小口径天线毫米波辐射计自然变温智能定标系统，该系统实现了所有数据的自动采集与分析。
In calibration of a infrared spectrum radiometer, we calibrate an infrared radiometer by measuring on various temperatures of the blackbody in order to reduce error.
在红外光谱仪的定标中，为了减小误差，可以选取多温度点的测量来进行定标；
Measurements can be made with an infrared radiometer. Blackbody radiation at the same temperature of the object is obtained using a cylindrical direct reflection cavity.
测量中使用了红外辐射计，并用圆柱形镜反射腔获得温度同地物相同的黑体辐射，并由已知比辐射率的参考板标定环境辐射。
