摘　　要：简述了进行高空间分辨率,高灵敏度微波辐射计研究的必要性。根据微波辐射计天线接收地物微波辐射的特性,讨论了三种提高微波辐射计空间分辨率的新技术:大口径天线技术、合成孔径技术、等效口径技术。为了适应未来星载微波辐射计新型扫描方式的要求,提出了结构简单、高稳定、高灵敏度的微波辐射计方案——计算机增益波动自动补偿微波辐射计。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.
