基于射线追踪法的航空多径信道建模与仿真

摘要

针对航空通信中由于复杂地形环境引入的多径影响，介绍了一种基于射线追踪法的多径信道建模与仿真的方法。 Wireless Insite 是一种基于射线追踪法的无线信道仿真软件，采用该软件，以实际项目为例，对多径信道建模与仿真的方法进行了详细介绍，并对仿真结果进行了分析。仿真结果表明了提出的建模仿真方法用于分析航空飞行器多径效应的有效性。%Aiming at the multipath effects in aeronautical communication due to the complex terrain,a method of multipath chan-nel modeling and simulation based on Ray Tracing method is proposed. Wireless Insite is a simulation software of wireless channel based on ray tracing method. By using this software,and based on the practical project,the multipath channel modeling and simulation method is introduced in detail. The simulation results show that the proposed modeling and simulation method can be used in analyzing the multipath effect of aerocraft.
