潜艇隐蔽攻击能力分析方法研究

Study on the submarine stealthy attack capability analysis method

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。

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 b^d on the accuracy and convergence time of estimation. In the end, some valuable results are obtained by simulation and analysis.
