【摘要】 水下目标的特征提取是声自导鱼雷目标识别和分类的基础,本文从水下目标的空间域信息的特征出发,讨论了分裂波束双通道自导系统目标方位提取方法,研究了基于目标方位扩展的水下目标方位起伏特征。实验表明,水下目标回波存在目标方位的起伏特征。更多还原

【Abstract】 The extraction of underwater target characteristics is the basis of the target recognition and classification for torpedo homing system.Taking the data characteristics of the spatial domain as the starting point in consideration,the bearing parameter extraction of the split beam dual-channel torpedo homing system and the fluctuation performance based on target bearing spreading are discussed in the article.Experiments have shown that target bearing fluctuation exists in underwater target echo.更多还原
