摘　　要：基于地外天体软着陆探测任务的需求,阐述了地外天体着陆自主避障制导技术的研究进展。首先对典型的地外天体着陆探测任务进行回顾与分析,并总结了着陆避障制导面临的形貌复杂多样、控制资源受限、避障精度要求高、星载计算资源有限等挑战与难点。在此基础上,从自主障碍评估和自主障碍规避两个方面梳理了着陆避障制导的研究现状。最后,结合未来地外天体探测任务需求,对着陆避障制导技术的发展方向进行了展望。Focusing on the requirements of extraterrestrial soft-landing exploration,the research progress of autonomous obstacle avoidance guidance technology for extraterrestrial landing is elaborated.Firstly,the typical landing missions on extraterrestrial body are reviewed and analyzed,and the challenges and difficulties faced by landing hazard avoidance guidance are summarized,such as complex and diverse topography,limited control resource,high hazard avoidance accuracy and limited on-board computing resources.On this basis,the research status of landing hazard avoidance guidance is reviewed from two aspects:autonomous hazard assessment and autonomous hazard avoidance.Finally,combined with the requirements of future extraterrestrial body exploration missions,the development direction of landing hazard avoidance guidance technology is prospected.
