摘要
纯距离测量条件下,对于静止目标,单观测站必须进行机动转向才可观测,根据可观测矩阵,提出可观测度的概念,推导出观测站一次转向机动时的优化航路,即观测站转向前后航向角度差为(观测站一次转向)。仿真结果表明,优化航路在定位精度、稳定性和跟踪速度方面性能方面最佳。
Only when the observer is in divertical motion,the target can be observed in the single-station range-only conditions.For the observability matrix,the observable degree is given,and the optimal trajectory of the observer is deduced,that is the difference of the observer＇s course angle（it means the observer make ninety degree turns）.The simulation result indicates that the optimal trajectory of the observer has better location precision、stability and tracking velocity than other trajectory.
