摘　　要：针对载人登月任务需要兼顾正常交会和应急交会,交会制导方案必须适应近圆和椭圆等不同轨道类型的问题,通过分析比较LAMBERT制导、T-H制导和C-W制导性能,对载人登月近距离交会制导策略进行了分析。提出分段使用LAMBERT制导和C-W制导设计近距离交会综合制导策略,数学仿真验证了所提出策略的有效性。研究表明:在寻的段LAMBERT制导的通用性更好,综合性能更具优势;而在接近段,C-W制导的综合性能更优。The manned lunar mission shall take into account both the normal rendezvous and the e-mergency rendezvous,and the guidance strategy must adapt to both of near-circle orbit and elliptical orbit.To solve this problem,the guidance strategy for manned lunar rendezvous was analyzed by com-paring the performance of LAMBERT guidance law,T-H guidance law and C-W guidance law.In this paper,the LAMBERT guidance law and C-W guidance law were used to design the comprehensive guidance strategy for near-range rendezvous.The effectiveness of the proposed strategy was verified by mathematical simulation.The results showed that LAMBERT guidance law had better performance in homing phase.In the approaching phase,the performance of C-W guidance law was better.
