面向水声探测识别的小目标特征提取研究进展

Research Advances of Small Target Feature Extraction for Underwater Acoustic Detection and Recognition

在水下防御的决策过程中,对蛙人、潜航器等入侵小目标的类别辨识直接关系到指挥控制系统对人员和武器的分配,并影响战斗走势。介绍了蛙人探测声呐研制进展、水下小目标探测识别框架。围绕特征提取这一关键技术,分别述评了回波类和噪声类的常见特征。分析了该领域面临的挑战,并展望了可行的研究方向。

During the decision-making of underwater defense,class identifications of small target such as frogman and unmanned undersea vehicle(UUV)are directly related to the allotment of personnel and weapons of command and control system.The trend of battle will certainly be affected.The development of diver detection sonar,basic recogniton framework of underwater small target are introduced at first.Then,focusing on the key technology of feature extraction,common features of echo and noise are reviewed separately.Finally,challenging problems and feasible research topics are presented.
