纯距离目标跟踪中的观测站机动航路优化研究磁

摘要

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 de-duced ,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 .%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。
