基于M-S图的舰船目标特征分布规律

摘要

在分析舰船物理场通过特性的基础上,根据“李萨茹图形”原理建立了舰船磁场与声场的李萨茹图形(M-S图),通过对M-S图进行的拟合,实现了舰船磁场和声场的联合特征提取；利用舰船磁场和声场仿真数据对特征量与航速、横距和深度之间的关系进行研究,得到了特征量的空间分布规律；将该分布规律应用于神经网络模式识别算法并对舰船目标进行识别,得到了较好的效果.%Based on the analysis of the characteristics of ship physical fields,this paper presents Lissojous diagram or M-S diagram for magnetic and sound fields.By fitting an M-S curve linearly,the extraction of common characters of magnetic and sound fields can be fulfilled.The analysis and simulation of different velocities,abeam distances and depths results in obtaining the spatial distribution rules of the characters.The rules are very useful to the neural network recognition algorithm for recognizing different states of three kinds of ships.
