| Abstract: | In this paper, the necessity of studying, high spatial resolution and high sensitivity microwave radiometer was introduced briefly. Accoding to the character of microwave radiation recived by microwave radiometer antenna, larde aperture, synthetic aperture,equivalent aperture antenna technologies were discussed.For adapting to new scanning type of future satellite microwave radiometer, a new microwave radiometer model which has structure simplicity, high stability,high sensitivity was suggested microwave Radiometer with Computer Controlled Automatic Gain Compensation. |
