| 摘 要： | 研究潜艇目标强度的统计特性对水中兵器的仿真和试验分析具有重要意义.本文针对直方图统计模型的精度受区间划分影响较大,提出将Parzen窗估计方法用于潜艇目标强度的统计建模,建立潜艇典型舷角下的目标强度分布模型,并对统计特性进行分析.对Benchmark潜艇模型进行仿真计算,结果表明,采用Parzen窗估计法建立的潜艇目标强度统计模型符合潜艇的物理结构特性,能够更加准确和有效地对潜艇目标强度的统计特性进行预报.

| Abstract: | The statistics characteristics research of submarine target strength (TS) have important value to thesimula-tion and experiment analysis of underwater weapon. Aimed at the problem that histogram statistics model precision is quite affected by area partition, Parzen window estimation method is used for submarine TS statistics modeling in this paper.Sub-marine TS distribution model in typical bow bearing is built and the statistics characteristics is analyzed. Benchmarksubmar-ine is used for simulation, the simulation results show that submarine TS statistics model by Parzen window estimationmeas-ures up to submarine physical structure property and it can forecast submarine TS statistics characteristics more accurately and more effectively. |
