摘　　要：为了将航海模拟器的功能从商船领域拓展到海洋渔业船员培训领域,这就需要在模拟器中增加渔船操作模块,并设计开发如网位仪等仿真设备。建立合理的回波强度模型,根据该模型自动选取相应的颜色级别以绘制海底回波图像,选取了简化的Floy鱼群运动模型、采用透明位图技术显示鱼群,最终实现海底、鱼群和噪声的动态显示。实现了与航海模拟器联网运行,得到了较好的仿真效果。The net recorder simulation equipment is developed and the fishery module is added to the navigation simulator in order to make it fit for training fishing vessel＇s seafarers. A reasonable model of acoustic echo intensity is developed. Seabed echo images are drawn with specified colors automatically according to echo intensity. The Floy model of shoal movements is used and the transparent bitmap technology is adopted to display the fish shoal. With those technology the dynamic display of seabed, fish shoal and noise are finally realized. Running the module with navigation simulator on a network shows good simulation results.
