- 在分析聚束合成孔径雷j盘(SAR)方位向时频关系的基础上,提出了一种新的全孔径分辨率SAR成像算法。 根据SAR在条带与聚束模式下回波信号之间的差别,利用现有成熟的条带SAR成像算法实现先对聚束SAR各方位向子 孔径成像,而后再将各方位子孔径带宽合成为全孔径带宽,以形成具有全孔径分辨率的SAR图像,极大降低了系统PRF 的要求。-In the analysis of spotlight synthetic aperture radar dish j (SAR) azimuth bas

- The Phase Gradient Autofocus (PGA) algorithm has been widely used in Spotlight Synthetic Aperture Radar (SAR) to remove motion-induced blurs in the images. The PGA algorithm has been proven to be a superior autofocus method. PGA assumes a nar
Non-Iterative-Spotlight-SAR-Autofocusing-Using-A-
- Phase-Gradient autofocus (PGA) technique is robust over a wide range of imagery and phase error functions but the convergence usually requires 4-6 iterations. In this paper, we propose to speed up the estimation convergence by selectively inc
