摘　　要：本文主要介绍了合成孔径的基本原理及合成孔径技术在国内外的发展研究进展,以及合成阵列的模型和信号模型,并且介绍了合成孔径技术在导航领域的基本应用,但现阶段由于技术不成熟以及硬件条件等的限制,此技术还未真正得到广泛应用,但基于单天线的合成孔径技术具有先天的优势,未来将有很大的发展前景.Tis paper describes the basic principles and synthetic aperture synthetic aperture technology research development status at home and abroad, as well as model and signal model in synthetic array and introduces synthetic aperture technology in the field of basic applications in navigation. But at this stage due to technical immaturity and hardware conditions, etc. , this technology has not yet been widely used. But based on synthetic aperture single antenna technology has inherent advantages, the future will have great prospects for development.
