The fundamental theory of the circular synthesis radar within a near field distance is analyzed firstly. Then based on the analysis, the key technologies and the main design parameters of the millimeter wave band system are summarized. Finally, the imaging results of a real system are shown and the corresponding problem is discussed.%对近场距离下圆柱合成孔径雷达系统的基本原理进行了分析,在此基础上总结了毫米波段系统实现的关键技术及系统主要技术参数设计依据,最后给出了实际系统的成像实验结果.
