摘　　要：随着蛙人侵扰活动的日益频繁,在一些重要的部位如港口、码头、海岸洞库和锚泊水域中都安装了水下监控系统,在这些系统中,基于反蛙人声纳的小目标检测既是研究的重点也是难点之一。文章针对小目标检测问题进行了讨论,提出反蛙人声纳图像处理和小目标检测算法。由实践结果可以得出,此算法具有较高的小目标检测率,有效提高了水下监控系统的可靠性。Diver invading incidents happens more and more frequently.Underwater surveillance systems are installed in some important area,such as port,dock,seashore depository and anchorage.In these systems,the detection of small target based on anti-diver sonar is the researching emphasis and difficulty.The key issues in small target detection is discussed in this paper.An sonar image processing and detecting algorithm of anti-diver is proposed.Practising results are presented and indicate that this algorithm is of high detecting rate,which increases the reliability of the underwater surveillance systems.
