摘　　要：激光雷达可以作为空间交会对接过程中的相对导航敏感器之一。本文基于线性H ill方程和经典双脉冲交会理论,给出一种两航天器多脉冲交会算法。结合激光雷达的测量值设计相对导航EKF滤波器。仿真结果表明通过滤波,激光雷达能够为航天器交会对接提供足够精度的相对位置和相对速度信息。Ladar is one of the guidance sensors in the spacecraft rendezvous and docking. Based on the linear Hill equations and classical two-pulse rendezvous theory, an algorithm of multi-pulse rendezvous is presented. According to the measurements of the ladar, the Extended Kalman Filter is designed for relative navigation. The results of simulation indicate that working together with the EKF, ladar can provide the information of relative position and relative velocity with sufficient accuracy for the spacecrafts rendezvous and docking.
