摘　　要：针对交会对接远距离和近距离交接的寻的段制导,提出一种基于Hohmann最优交会的制导方法。先给出邻近圆轨道交会动力学方程;结合寻的段飞行时间特点给出Hohmann最优交会并分析其应用范围;针对寻的段存在相对测量的特点提出一种CW制导和Hohmann最优交会结合的多脉冲制导策略,并给出仿真算例,仿真结果验证了方案设计的有效性和正确性。A homing guidance method based on Hohmann optimal rendezvous was proposed for rendezvous and docking from long distance to short distance. The dynamic equations for circular orbit rendezvous were given. According to the homing flight time, a Hohmann optimal rendezvous was given and its application scope was analyzed. In addition, a multi-impulse guidance strategy combining CW guidance with Hohmann optimal rendezvous was proposed considering the relative measurement in the homing phase. Then a simulation example was given and the effectiveness and accuracy of the guidance design was verified by the simulation results.
