Application of HT-TBD in Passive Detection of Underwater Targets

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.
