【摘要】 针对复杂背景条件下声目标的自动识别问题,设计了一种基于模糊综合评判的声目标识别系统.该系统在对典型战场声目标特征进行充分提取与选择的基础上,建立反映目标类属特征的隶属函数库,采用先进的模糊综合评判技术实现对目标的可靠识别.对特征提取与选择、隶属函数确定、模糊评判、原理样机实现等关键问题进行了详细的讨论.实测检验表明,该系统对战场声目标具有良好的识别分类效果.更多还原

【Abstract】 In view of the automatic recognition problem of acoustic targets under the condition of very indetermination background, a kind of fuzzy pattern recognition system based on fuzzy synthesis judgment was designed. On the basis of sufficient feature abstract & choice for the typical battlefield acoustic targets, this system establishes a subjection function bank of indicating the targets type characteristics, and realizes the recognition to different acoustic targets using advanced fuzzy synthesis judge technology. The key problems about the feature abstraction & choice, subjection function constitution, fuzzy synthesis judgment and principle prototype realization were discussed. The practical test shows that this method has well recognition effect to battlefield acoustic targets.更多还原
