The invention relates to a multi-pulse region hovering method based on small planetary surface observation, and belongs to the technical field of aerospace. The multi-pulse region hovering method based on small planetary surface observation considers small planetary irregular gravity and solar radiation pressure perturbation, and designs a hovering track meeting a small planetary surface hoveringarea constraint based on a targeting method; and the optimal power consumption is the performance index, and the obtained hovering track is minimum in total speed increment under a specific correctionduration constraint. The method has the advantages of being small in required speed increment, few in application pulse times, wide in application range, capable of meeting the hovering area constraint of different sizes, and suitable for hovering track design under the constraint condition of a small planetary surface hovering area. 本发明涉及一种基于小行星表面观测的多脉冲区域悬停方法，属于航空航天技术领域。本发明公开的一种基于小行星表面观测的多脉冲区域悬停方法，考虑小行星不规则引力和太阳光压摄动，基于打靶法
