摘　　要：弹载SAR是SAR和精确制导研究的交叉领域,SAR导引头已成为当前导引头研制中的一个热点。首先讨论了弹载SAR技术主要的四个应用方向:修正惯导误差、打击时敏目标、攻击点选择和毁伤评估,分别介绍了其工作原理,然后通过分析弹载SAR的特点讨论了弹载SAR技术应用中有待于解决的问题,对国外弹载SAR相关系统的研制和国内外相关技术的研究进行了较为全面的综述,最后介绍了由于SAR技术的引入而可能诞生的新体制导引头。Missile-borne SAR is the interdisciplinary research area of SAR and Precision Guidance, and it has become a hot spot of seeker development. The four main applications of missile-borne SAR, Inertial Navigation System error compensation, time-sensitive target observation, aiming point selection and hitting effect evaluation, are introduced. The key problems emerging with missile-borne SAR are discussed by comparing missile-borne SAR with space-borne and airborne SAR. A general overview of missile-borne SAR systems and techniques development is provided, followed by description of potential seekers brought out by the application of SAR in Precision Guidance.
