本文介绍了一种新的模拟方法来评估民用港口设施的水下安全水平，旨在弥合系统规格与防入侵系统运行性能之间的差距。将地理信息系统（GIS）、声学和磁传感器模型与动态模拟器相结合，可以模拟新传感器和传感器在整个港口保护系统中放置的修改的影响。利用该方法可以对港口环境进行建模，包括地理和环境信息，建立水声、磁传感器和再捕获车辆的监控系统，并添加几种类型的入侵者，通过动态模拟来估计所选入侵者所选择的传感器配置所获得的安全级别。其目的是隐藏声波和磁传播的物理方面，同时提供高水平的价值数字（阻止入侵者的概率，与高价值资产（HVA）的预期半距离，以及拦截的预期半时间），能够清晰地表示系统检测、分类和阻止威胁的能力。为此目的，开发了一种软件模拟器工具，并报告了它在几种情况下的使用情况（例如，传感器的配置和部署，对变化的海洋条件的性能敏感性）。
This paper introduces a new simulative approach to assess the level of underwater security in civilian harbor installations, with the aim of bridging the gaps between system specifications and operative performance of anti-intrusion systems. The integration of a geographical information system(GIS), acoustic and magnetic sensor models, with a dynamic simulator makes it possible to simulate the impact of both new sensors and modification in the sensors placement in the overall harbor protection system. With the proposed approach it is possible to model the harbor environment including geographical and environmental information, to set up the surveillance system with underwater acoustic and magnetic sensors and reacquisition vehicles, and to add several types of intruders to estimate, through dynamic simulations, what security level is obtained by the sensors configuration chosen against the selected intruder. The intention is that of hiding the physical aspects of acoustic and magnetic propagation while providing high-level figures of merit (probability to stop the intruder, expected halt distance from the high value asset (HVA), and expect halt time to intercept) capable of a clear representation of the system capability to detect, classify, and stop a menace. For this purpose, a software simulator tool has been developed and its usage in several scenarios has been reported (e.g., sensors configuration and deployment, performance sensitivity to changing oceanic conditions).
