摘要
对于计算威胁区通视性的四种方法进行了分析与实验比较。所谓通视性分析（Ｖｉｓｉｂｉｌｉｔｙａｎａｌｙｓｉｓ）就是分析在三维空间中观察者发现目标的概率。通视性分析是飞行航路规划的基础，对于选择一条安全的航路具有重要意义。通视性分析的主要任务是找出使飞行器能够躲避给定的观察者，如雷达站、空中预警飞机和拦截飞机等区域。在这些区域中，飞行器具有最小被发现概率。选择那些使飞行器具有最小被发现概率的航路，可以大大增强飞行器的生存概率。文中讨论了四种通视性方法即点到区域法、快速点到三角形法、次快速点到三角形法、消隐法，并进行了实验比较。
Four approaches for calculating the visibility of threatened area are analyzed and compared with experiments in this paper. Visibility analysis is used to analyze the finding probability of the target detected by observers in three dimensional space. The visibility analysis is the foundation of route planning and it is important for choosing a safe route. The main work of the visibility analysis is to find hidden area which is not visible to the observers, such as radar,air pre alarm aircraft,interceptor etc. The more the flight route is planned to pass through hidden area, the safer the aircraft is. This paper discusses four algorithms: point to region algorithm, fast point to triangle algorithm, point to triangle algorithm, hidden removal algorithm, they are compared with the experiments.
