掩埋小目标声探测技术研究

探测和识别沉底、掩埋水雷等小目标在军事上显得愈来愈迫切。在介绍掩埋小目标探测声纳现状的基础上,剖析了掩埋小目标声探测的技术难点,总结了小目标声探测技术的发展趋势,主要包括探测频率向低频发展,重点发展合成孔径探测技术,积极探索时反探测和MIMO探测方法,小目标识别技术向联合利用图像特征和散射特征的方向发展等,对沉底/掩埋小目标声探测技术研究及其声纳设计有借鉴指导意义。

Review of current status of buried-object detection techniques

Detection and recognition of small objects,such as bottom-mine and buried-mine etc.,becomes imminently and imminently in military application.Following an introduction of state-of-the-arts of small buried-objects detection,the paper intensively analyzes the technical difficulties of small buried-object detection and summarizes the developing trends of buried object detection by using acoustic techniques,which included： lowering the operation frequency,de-veloping detection techniques of SAS（Synthesized Aperture Sonar）,exploring time-reversal and MIMO detection methods,recognizing small-object jointly using image and scattering signatures,and so on.These are significant guiding technical research and relevant sonar design on small-object detection.
