地空通信信道模拟器研究

Research on Channel Simulator of Ground-Air Communication System

介绍一种用于模拟地空通信实际链路的信道模拟器,通过软硬件结合的方式,实现了可同时模拟6根多径信号信道模拟器。采用真实的通信信号发生器,可直接用于接收机的性能测试。采用良好的人机界面,可以使操作手直接了解在飞机不同区域、不同地形情况下的地空通信质量。对于多径敏感区域,模拟器支持反复飞行或悬停状态,可以替代飞机飞行,满足日常训练需求。

This paper introduces a channel simulator of ground-air communication system which can be used to simulate six routes multipath channel signals by combining hardware with software. The Channel Simulator can be used to test receiver performances by using real communications signal generator. Its good human-computer interaction can make the operator know the ground-air communication quality of airplane in different regions and different terrain conditions. It can sustain the plan repeat flying or poising in multipath sensitivity area to replace airplane to satisfy the requirements of routine training.
