来自海上的恐怖主义和利用水空间的海上犯罪的可能性趋于增加，并且需要水下监测和可视化技术的发展。我们研制的船载水声监视系统，通过将声纳安装在船上，可以在水面上进行大范围的监视，具有机动性。该系统是一种高分辨率的水下可视化声纳系统，能够在真实的图像和真实的时间内有效地检测和区分目标。该系统不仅可用于在目前无法观测到的水域中发现可疑人员或可疑物体，而且可用于沉船搜寻、水下安全和港区调查等。简要介绍了水声监视系统的工作原理和成像原理，并给出了在实际海域的运行试验结果介绍了在试验船上安装声纳的方法。
Possibility of terrorism from the sea front and maritime crimes using the water space tends to increase and development of underwater monitoring and visualizing technology would be desired. We developed the ship-mounted underwater acoustic surveillance system which can watch widely in the water space with mobility by mounting the sonar on ship. This is an underwater visualization sonar system with high resolution that efficiently detects and distinguishes the targets in real image and in real time. It is expected that this system is useful not only for finding of doubtful person or doubtful objects in the water in which we cannot observe until now but also for search of the sunken ship, underwater security and investigations in the harbor area and so on. In this paper, mechanism and imaging principle of the underwater acoustic surveillance system are briefly described and results of the operational test in the actual sea area carried by mounting the sonar on the test ship are introduced.
