摘要
多平台合成孔径雷达(SAR)是合成孔径雷达极具发展潜力的研究方向之一,该文集中讨论了多平台SAR的成像算法,包括机载SAR、弹载SAR和星载SAR平台。该文首先简要阐述了SAR回波模型的建立,包括“斜距模型和成像模式”,然后综述了近年来机载SAR、弹载SAR和星载SAR成像算法的研究进展,并详细阐述了各平台固有的特性以及面临的挑战,最后对未来多平台SAR成像算法研究的发展趋势进行了展望。
The multi-platform-borne Synthetic Aperture Radar(SAR)has become one of the most explored research directions in the domain of SAR.This study discusses the imaging algorithms in multi-platform-borne SARs such as airborne SAR,missile-borne SAR,and spaceborne SAR.First,the establishment of the radar echo model is briefly introduced,including two main points:slant range-model and imaging mode.Subsequently,the imaging algorithms of the aforementioned multi-platform-borne SARs developed and used in recent years are summarized.In addition,the inherent characteristics and challenges are described.Finally,the future development trends of the research are discussed.
