摘　　要：目前,线上教学已成主要授课方式。针对传统客户端/服务器(Client/Server,C/S)架构的航海雷达模拟器通用性差、使用受时间与空间限制、不能开展线上实操培训等问题,设计了一种基于浏览器/服务器(Browser/Server,B/S)架构的航海雷达仿真系统。提取S-57海图中有关数据,并采用边界线裁剪、分类存储等操作生成雷达仿真数据;使用道格拉斯-普克(Ramer-Douglas-Peucker,RDP)算法简化回波数据,提高回波处理与绘制效率;采用圆周扫描方式生成岸线、固定物标等回波数据,集中绘制,提高了绘制效率;通过扇形裁剪双层透明杂波图像,实现杂波的径向圆周扫描;通过对历史回波数据分类、记录、提取、转换等操作,实现尾迹的模拟。仿真结果表明,该系统功能完备,运行稳定、可靠,可用于航海雷达的在线教学与培训。Currently,online teaching has become the main teaching method. Aiming at the problems of poor generality,limitation of time and space,inability to carry out online practical training of traditional C/S marine radar simulator,a marine radar simulation system based on B/S architecture is designed. The relative data from the S-57 maritime map are extracted,and boundary line trimming,classification storage and other operations are used to generate radar simulation data;Ramer-DouglasPeucker(RDP) algorithm is utilized to simplify echo data to improve echo processing and drawing efficiency;the circular scanning mode is used to generate echo data such as shorelines and fixed objects,and they are centrally drawn to improve the drawing efficiency;the radial circular scanning of clutter by sector trimming of the double-layer transparent clutter image is realized;the simulation of trails by classifying,recording,extracting,converting and other operations of historical echo data is realized. The simulation results show that the system has complete functions,the operation is stable and reliable,and the system can be used in online teaching and training of marine radar.
