摘要:
随着精确着陆技术的发展,探测器在行星表面可到达的地区形貌状况越来越复杂。为了保障着陆的安全性,在下降过程中探测器需要结合敏感器信息对视野范围内的着陆区形貌进行评估分析,从而选取出最适宜着陆的地区。针对这一问题,本文提出一种行星安全着陆点选取思路,并设计出着陆点选取的参考指标,通过对形貌以及燃耗的评估,实时选取安全着陆点。MATLAB仿真结果表明,针对快速选取过程和遍历选取过程,该方法均能够在两种过程中有效选取出满足要求的着陆点,从而提高了任务的成功率与安全性。

Abstract:
With the development of precise landing technology,the terrain condition of the area that the vehicle can reach will be more and more complex. To ensure landing safety,the vehicle needs to assess the landing area topography in the field of view based on the sensor information and picks out a place suitable for landing. In order to solve this problem,the paper proposes a planetary landing site selection method and designs a referential selection index. The safe landing site is chosen according to the evaluation result of terrain condition and fuel consumption. MATLAB simulation proves the effectiveness of the method in both rapid selection process and traversal selection process,which improves mission success probability and landing safety.
