摘要
在脉冲样本图骨架周期存在估计误差的情况下,测量TDOA的完全非共视定位算法性能会随着外推时间长度的增加而下降。针对这一问题,提出一种校正算法,通过同时估计骨架周期和辐射源位置并迭代计算的方式,可有效减小骨架周期估计误差对定位性能的影响,仿真结果证明该算法的有效性。
In case of an estimation error in the pulse sequence pattern skeleton period,the performance of absolutely uncommon-view location algorithm by measuring TDOA will decrease in according with the increase of the extrapolation time.For this problem,a correction algorithm by simultaneously estimating the pulse sequence pattern skeleton period and emitter’s position and calculating iteratively is proposed,effectively reducing the effect of pulse sequence pattern skeleton period estimation error on positioning performance,and the simulation results show the effectiveness of the algorithm.
