综合孔径微波辐射计利用干涉测量把小口径天线阵列综合成大的观测口径,是一种可以有效提高空间分辨率的无源微波遥感传感器。分析了综合孔径微波辐射计成像过程,采用一维孔径综合与机械扫描相结合的方法实现微波辐射成像,设计数字微波辐射计阵列成像的控制系统;用LabVIEW开发控制软件。实验结果表明：控制系统能够精确控制微波辐射计阵列进行二维成像,数据采集系统各通道之间的采样偏差为20 ps以下,扫描角度可以精确到0.1°。

英文摘要：

The synthetic aperture microwave radiometer （SAMR） is a passive microwave remote sensor, it can achieve better resolving power based on interferometric measurement with an antenna array that uses a relatively small number of individual elements. This paper analyzed the imaging process of SAMR, using one-dimensional aperture synthesis and integration of mechanical scanning method to image microwave radiation, designed the imaging control system of digital microwave radiometer array; developed the of control system software by LabVIEW. The results showed that the control system can precisely control microwave radiometer array 2D imaging, the sampling error is below 20 ps between different channel of data acquisition and scanning angle precise is 0. 1 degrees.
