| 摘 要： | 为实现主从式卫星编队飞行中心星与环绕星的自主定轨，采用微波雷达测量卫星间相对距离、距离速率、方位角和仰角。根据动力学方程给出了导航算法，并利用扩展卡尔曼滤波（EKF）提高微波雷达相对速度的测量精度。仿真结果表明，该导航算法对主从式卫星编队较有效，且能获得较佳的导航精度。

| Abstract: | To realize the autonomous of master satellite and tributary satellite in forming with one master satellite and several secondary satellites, the relative range, range rate, azimuth and elevation were measured through microwave radar in this paper, The navigation algorithm was derived from the kinetic equation, and the extended Kalman filter was applied for improving the measurement accuracy of relative velocity of microwave radar, The simulation results showed that the algorithm was effective to forming of master and secondary satellite, and would acquire high accuracy. |
