摘要
以两飞行器自主交会、绕飞与最终逼近为背景 ,研究基于交会雷达的自主相对导航方法。基于间接测量量设计了扩展Kalman滤波器 ,并设计了具有自调整功能的测量误差协方差矩阵R。
Taking autonomous homing, flying-by and final approaching of two spacecrafts in space as background, the autonomous relative navigation algorithm is studied in this paper. Based on the indirect measurements, the extended Kalman filter is designed, and the self-adjusted error covariance matrix R is given. The validity of this method is proved by the simulation results.
