摘　　要：航天器进入、下降和着陆过程是深空探测任务最为重要的阶段之一,着陆雷达是实现定点、安全软着陆的重要保障。文章系统地总结了以"阿波罗11号"、"嫦娥三号"、"嫦娥四号"为代表的月球探测器、以历次成功着陆火星任务为代表的火星探测器以及以"隼鸟号"、OSIRIS-Rex为代表的小行星探测器任务中着陆雷达技术的发展和应用,对着陆雷达技术未来发展的趋势及所面临的挑战进行了展望与分析。The entry,descent,and landing(EDL)system is one of the critical process to the successful landing of deep space explorations.Landing radar assures the capability to land accurately and safely.This paper systematically summarizes the development and application of landing radar in deep space explorations.The missions listed in this paper include lunar landers and asteroid explorers,such as Apollo-11,CE-3,CE-4,Hayabusa,OSIRIS-Rex,and successful MARS missions.Furthermore,the development trend and challenge are also prospected and analyzed.
