距離向多孔徑超寬測繪帶成像體制中各項誤差分析
Error Analysis About Range Multi-aperture SAR Imaging System
-
摘要: 理論上已經(jīng)證實可實現(xiàn)超寬測繪帶的距離向多孔徑成像方法在增加測繪帶寬的同時又可獲得較高的分辨率.為了正確地評定距離向多孔徑成像方法的實用性,該文給出了體制中各項誤差的定量分析,并對一些誤差給出了相應(yīng)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. -
