摘要

在传统的带扫描天线的星载微波辐射计系统中，常常存在空间分辨率与辐射分辨率之间的冲突。为了提高辐射分辨率，可能需要对每个频率的多个波束进行积分。许多光束可以使用许多经典馈电喇叭或由焦平面阵列(FPA)系统产生。c波段的喇叭体积庞大，用FPA代替几个这样的喇叭是一个有趣的选择。

Future High-Performance Spaceborne Microwave Radiometer Systems

In a traditional spaceborne microwave radiometer system with a scanning antenna there is often a conflict between spatial and radiometric resolution. Integration over many beams per frequency might be necessary to improve radiometric resolution. Many beams may be generated using many classical feed horns or by a Focal Plane Array (FPA) system. At C-band horns are bulky and replacing several such horns with a FPA is an interesting option.
