水下探测声呐在半潜式平台水下安防系统中的应用

Application of Underwater Detection Sonar in Underwater Security System of Semi-submersible Platform

将水下探测声呐应用于半潜式采油平台对非法入侵的水下蛙人、潜行器和水下外来人员等目标进行实时探测预警,必要时采用防卫机制人工将目标驱离限定水域。从声呐图像预处理、运动目标检测和轨迹跟踪等3个方面详细设计水下声呐探测方案,并对探测方案进行应用试验。结果表明该方案可有效检测目标并进行轨迹跟踪,验证了水下探测声呐应用于半潜式平台水下安防系统中的有效性。

The underwater detection sonar is applied to the semi-submersible oil production platform for real-time detection and early warning of illegal underwater frogman,stealth vehicle and alien underwater personnel.If necessary,the defense mechanism is adopted to drive the target away from the restricted waters.The underwater sonar detection scheme is designed in detail from three aspects:sonar image preprocessing,moving target detection and trajectory tracking.The application test of the detection scheme is carried out.The results show that the scheme can effectively detect the target and conduct trajectory tracking,which verifies the effectiveness of underwater detection sonar applied in the underwater security system of semi-submersible platform.
