无线电高度表综合检查仪的设计

设计了一种航空无线电高度表综合检查仪,可以定点输出虚拟的无线电高度信号,以标校对应飞参数据采集通道的采集误差,同时还可以实现射频信号通道衰减量控制,可对机载无线电高度表测高精度、搜索灵敏度和跟踪灵敏度进行在线检测。该检查仪对于提高地勤维护的快速性和准确性具有重要意义。

Design of Radio Altitude Parameter Calibration Instrument

An aviation radio altimeter integrated detector is designed,which can produce fictitious radio altitude signals used to calibrate sampling errors of corresponding flight data collecting channels.At the same time,it can also control the attenuation of radio-frequence signals and detect the height accuracy,searching sensitivity and tracking sensitivity of radio altimeter on-line.The integrated detector has great significance for improving the speediness and exactness of ground maintenance.
