The W Band Radiometer for Imaging

摘要：

The paper describes a W band radiometer for imaging. A superheterodyne receiver with Dicke switch is used in this radiometer, whose millimeter-wave components, which include a millimeter-wave fundamental wave mixer, a harmonic mixer and a VCO are mounted on the back-end of antenna for lower transmission loss. By this means, the radiometer with sensitivity 0.5k is achieved. Through the experiment of imaging, the radiometer is shown to meet the requests of the image system.
