摘　　要：在弱目标检测研究中,HT-TBD检测算法是1种有效的理论方法。针对现有水下弱目标被动检测的难题,提出1种适用于水下目标被动检测的HT-TBD算法。首先,阐述HT-TBD检测思路,在分析声呐浮标检测组检测预处理基础上,研究基于TBD理论和Hough变换的水下目标被动检测算法;其次,围绕浮标阵型适用场景,分析探测设备指标、环境场地指标、目标指标及干扰指标,给出拦截阵和覆盖阵2类试验方案及步骤;最后,在新安江水库对2类试验场景数据进行采集和预处理。结果表明:通过实测数据和MATLAB仿真验证了HT-TBD检测算法在水下弱目标检测的可行性和有效性。In the research of weak object detection,the HT-TBD detection algorithm is an effective theoretical method.A HT-TBD algorithm suitable for passive detection of underwater weak targets is proposed to address the challenges of existing passive detection methods.Firstly,the HT-TBD detection concept is elaborated.Based on the analysis of the detection preprocessing of the sonar buoy detection group,a passive underwater target detection algo‐rithm based on TBD theory and Hough transform is studied.Secondly,focusing on the applicable scenarios of buoy formation,the detection equipment indicators,environmental site indicators,target indicators,and interference indi‐cators are analyzed,and two types of experimental plans and steps for interception array and coverage array are pro‐vided.Finally,data from two types of experimental scenarios are collected and preprocessed at the Xin'anjiang Res‐ervoir.The feasibility and effectiveness of the HT-TBD detection algorithm in underwater weak target detection are verified through measured data and MATLAB simulation.
