摘要
分析了合成孔径雷达实时成像的系统设计瓶颈,研究了距离子带划分与方位预滤波的处理方法,并提出了一种高性能的机载实时成像系统设计。该系统不仅能够有效满足雷达成像大幅宽、高分辨的实时处理需求,而且还具有优良的拓展能力,兼容性好。实际处理结果验证了该设计方法的有效性。
The difficulty of real-time synthetic aperture radar（ SAR） processing is analyzed. The method of azimuth pre-filtering and range dividing is studied. A system structure is presented for high quality real-time SAR processing,which is not only suitable for high resolution and wide width,but also can be extended easily and has good compatibility. All concepts are verified by practical processing results.
