摘　　要：从仿真海上无线传输的实际需求出发,设计代入感更强、数据实时性更高的海上无线传输仿真平台,将可视化技术与海上无线信道模型相结合,取代传统的偏向于数学公式和图表的仿真方法。对传统的海上无线信道模型进行改进,将自由空间损耗、反射损耗、绕射损耗和大气损耗相结合,构建应用性更强,频段涵盖范围更广的信道模型;用Unity3D恢复真实场景并实现环境配置和角色控制;将后台海上无线信道模型的计算结果与前台场景相结合,在虚拟环境中实时显示通信质量和信道变化。Based on the actual demand of simulating wireless transmission on the sea, a simulation platform with stronger immersion and more real-time data is designed, which combines visual simulation technology and maritime wireless transmission to replace the traditional methods which just build mathematical charts and tables. The traditional channel models are improved and a connection among the free space path loss, reflection loss and so on is built. Different models aim to different communication bands for establishing a widely used transmission. Unity 3D game engine is used to recover a real scene and realize environment configuration and roles control. The foreground displays and the background computing results are integrated to make the real-time display of communication quality and channel variation come true.
