摘要:
纯方位角无源定位时，观测平台的运动轨迹对目标最终的定位精度有重要影响。针对之前在求取观测平台最优轨迹时限制条件多、算法可能只是局部最优的问题，提出了一种观测平台的单步最优轨迹算法。计算机仿真算例表明：与通常的最优观测平台轨迹算法相比，该算法在求解最优轨迹时只需已知观测平台的初始状态，同时算法不受观测次数和终止条件的限制，具有较强的工程实用性。
Abstract:
The observer’s trajectory has an crucial importance on the accuracy of bearings-only target localization.Aiming at the problems of much excessive restriction conditions and partial optimization that existed in former algorithms,an one-step optimal algorithm for designing observer’s trajectories was proposed.A computer simulation example illustrated that the observer’s trajectory was only determined by the observer’s initial states,and the algorithm was not limited to the times of observations and the restriction of terminating conditions.Compared with normal methods,the algorithm has better practicality.
