摘　　要：为满足某型机遥测数据采集与传输系统地面接收设备检测、人员训练、故障排查的需要,利用机载遥测设备记录的原始数据,结合计算机及软件设计,模拟出机载数据;再采用具有COFDM调制技术的无线网络电台、高增益全向天线等硬件设备,与地面接收设备组成一个无线传输网络,模拟出机载数据的采集、传输等功能,从而实现在机载遥测设备不参与工作的情况下,完成地面接收设备的上下行链路无线闭环检测等工作。In order to meet the needs of ground equipment detection,personnel training and trouble shooting in telemetering data acquisition and transmission system of a certain type of aircraft,using raw data recorded by airborne telemetry equipment,combining computer and software design,the airborne data is simulated.Then the hardware equipment such as wireless network radio station with COFDM modulation technology,high gain omnidirectional antenna and so on is adopted,a wireless transmission network is formed with the ground receiving equipment,simulation of airborne data acquisition and transmission function,so as to realize that in the case where the on-board telemetry equipment dose not participate in the work,the up-and-down link wireless closed-loop detection of equipment is completed.
