摘　　要：文中分析了飞机处于停场、滑行、起飞、降落时飞机四种状态的航空无线信道模型,提取了四种状态下典型信道参数。同时针对航空通信中的宽带系统,通过信道化处理方法,将宽带信道划分成多个并行的窄带信道,设计了一种宽带航空信道模拟系统,可用于解决硬件平台受限于A/D采样速率的瓶颈,降低硬件运算时间,该模拟系统可以完成飞机不同状态下,航空通信的系统设计验证。This paper analyzes the aeronautical channel model when plane is in parking,taxiing,landing/take-off or en-route scenario.The typical channel parameters of these four scenarios are proposed.By using channelized method,wide-band channel could be divided into multiple parallel narrow-band channels.A wide-band aeronautical channel simulator is designed,which could be used to solve the bottleneck problem of hardware platform limited by A/D sample ratio when the signal is wideband and decrease running time of the hardware.This simulator could validate the system design of aeronautical communication with plane in various scenarios.
