【摘要】 本文以空间飞行编队为对象,基于多源纯角度量测,研究了高速目标飞行器的跟踪定位方法。首先,在地心(固连)坐标系中建立了编队飞行器及目标飞行器的运动学和动力学方程,在当地量测坐标系中给出了角度量测模型。基于仿真实验,分析了测向交叉融合定位算法、最小二乘融合定位算法、基于EKF和UKF非线性滤波的定位算法,得出了若干有意义的结论。更多还原

【Abstract】 The high-speed target tracking and localization are investigated based formation spacecrafts with bearings only measurements in this paper.The kinematical and dynamic equations of the flight vehicles are firstly set up in the Earth-Centred Earth-Fixed Frame(ECEF),and the measurement models are also presented in the local reference frame.Two geometrical localization schemes and nonlinear filtering based algorithms are analyzed through a variety of simulation experiments.Some interesting and significant results are obtained.更多还原
