摘要 为了实现对机载合成孔径雷达 (SAR)数据的实时成像处理 ,提出了一种基于数据划分的机载合成孔径雷达实时成像处理系统的硬件平台结构 ,分析了它的优点和约束规则 .根据机载 SAR距离多普勒 (RD)成像算法 ,提出了基于数据处理粒度的 SAR成像处理实时性的分析方法 ,并对机载 SAR实时成像处理系统进行了分析 .给出了实时成像处理机的实现 。 In order to realize the real-time imaging for airborne synthetic aperture radar (SAR), the architecture of a data dividing based airborne SAR real-time imaging system is discussed, and its merits and constraints are analyzed. Aimed at range Doppler (RD)imaging algorithms, the real-time analysis based on granularity is proposed, and the implementation of a real-time imaging system is given. Imaging results with raw data are in agreement with the theoretical analysis.
