自20世纪50年代初发明以来，合成孔径雷达（SAR）由于其具有吸引人的能力，如在距离和横向维度上提供良好的分辨率，而受到越来越多的关注。虽然机载和星载合成孔径雷达系统的主要用途是监视和地球物理遥感，但合成孔径雷达在许多领域，从地下成像到作物监测，都有许多应用。本文从合成孔径雷达的发展历史入手，介绍了合成孔径雷达信号处理的基本原理，包括距离压缩和方位压缩。介绍了合成孔径雷达成像的应用和一些常见问题。介绍了逆合成孔径雷达（ISAR）的基本原理及其应用。先进的合成孔径雷达的概念，如运动补偿，干涉合成孔径雷达（IFSAR），极化合成孔径雷达（POLSAR）成像。文章最后讨论了合成孔径雷达成像中的一些热点问题和新兴技术。

Since its invention in the early 1950s, synthetic aperture radar (SAR) has gathered increasing attention thanks to its attractive capabilities, such as providing good resolutions both in range and cross-range dimensions. Although primary exercises of airborne and spaceborne SAR systems were for surveillance purposes and for geophysical remote sensing, numerous applications of SAR have been implemented in many areas, from subsurface imaging to crop monitoring. This article begins with the history of SAR and presents the basic principles in SAR signal processing, including range and azimuth compression. Applications and some common problems in SAR imagery are covered as well. Principles of inverse synthetic aperture radar (ISAR) and its applications are demonstrated with examples. Advanced SAR concepts such as motion compensation, interferometric SAR (IFSAR), and polarimetric SAR (POLSAR) imaging are also presented. The article is concluded by discussing some hot topics and emerging technologies in SAR imagery.
