摘要: 理论上已经证实可实现超宽测绘带的距离向多孔径成像方法在增加测绘带宽的同时又可获得较高的分辨率.为了正确地评定距离向多孔径成像方法的实用性,该文给出了体制中各项误差的定量分析,并对一些误差给出了相应的算法上的修正.Abstract: Range multi-aperture imaging algorithm is proved by theory that it can widen the swath and obtain high resolution at the same time. To evaluate the practicality of range multi-aperture SAR system, this paper gives quantitative errors analysis of this system and presents the corresponding amendment to the imaging algorithm.
