水压引信目标分类的研究

Target Classification in the Mine's Hydrodynamic Fuze

本文提出一种模糊统计分类 FSC 方法,用于研究水压引信目标分类问题。在建立水面目标场多级网络分类模型的基础上,分析讨论了此方法的特征提取、识别函数、模糊与冲突、搜索算法等技术问题,并通过仿真实验,对水面目标航速、吨位、横距进行分类处理,结果表明,FSC 方法行之有效。

In the modern underwater mines,it is important to use the hydrodynamic fuze.Many authors have done a great deal of research work on target detection in the field [1],and some techniques have been applied to the Ordnance Stonefish of UK,new generation mine[2].But up to now,to the author's best knowledge,no papers have been reported in the open literature on target classification in the field,especially on target range classification. It is just the purpose of this paper to develop the surface target classifica- tion in the mine's hydrodynamic fuze.The two major contributions are as follows: (1)In order to dl with this problem,the new approach of combining Fuzzy with Statistic method is proposed,and we discuss its preprocessing, feature extraction and selection,fuzzy-statistical function,and algorithm. (2)With this approach,the problem pattern is separated into three sub- patterns,target speed,size and range pattern;the relation among subpatterns is analysed,and then the multiple level model for classification is constructed. In this paper,finally,the results of the simulations and experiments are given to show that the approach presented is flexible,uncomplicated,quickly sortable,and easily implemented.
