摘要: 纯方位定位系统是复杂的非线性系统,所有的估计算法都是次优的。理想估计器是工程估计器的性
能上限,在理想估计器下的潜艇隐蔽攻击效率是最高的,针对其在工程上无法实现,讨论了这种最大值的数量特
性。提出了“隐蔽攻击能力上限”的概念,分别给出了求解估计器精度和收敛时间意义下隐蔽攻击能力上限的仿2
真流程。最后,进行了计算机仿真试验和结果分析,得到了一些有价值的结论。

Abstract : Bearings only location system is a sophisticated nonlinear system , and all the estimation algorithms are
sub optimal. Because an ideal estimator is the upper limit of the properties of the engineering estimators , the attacking
efficiency of the submarine adopting this estimator is believed to be the highest. These quantity characters are studied
based on the nonlinear property of bearings only estimating system. The notion of“upper limit of submarine stealthy
attack capability”is presented and detailed. The simulation flow is provided to work out this capability based on the ac
curacy and convergence time of estimation. In the end , some valuable results are obtained by simulation and analysis.
