The invention provides a method and system for processing glide monitoring signals in an instrument landing system, and the method comprises the steps: carrying out the down-conversion processing of three paths of space sampling analog signals obtained from the output parts of three paths of radiation antennas, and obtaining three paths of original intermediate-frequency digital signals; performing signal synthesis on the three paths of original intermediate-frequency digital signals to obtain an intermediate-frequency digital position monitoring signal, an intermediate-frequency digital width monitoring signal and an intermediate-frequency digital clearance monitoring signal; and performing up-conversion processing on the intermediate-frequency digital position monitoring signal, the intermediate-frequency digital width monitoring signal and the intermediate-frequency digital clearance monitoring signal to obtain corresponding three paths of radio frequency analog monitoring signals. By adopting the method, the problems that the output signal of the monitoring signal synthesis unit in the traditional instrument landing system cannot truly reflect the actual input of the monitoring signal synthesis unit, and the index detected by the monitor cannot truly reflect the actual condition of the antenna radiation signal are solved.

    本申请提供一种仪表着陆系统中下滑监测信号的处理方法及系统,方法包括:对从三路辐射天线的输出处获取的三路空间取样模拟信号进行下变频处理,得到三路原始中频数字信号;对三路原始中频数字信号进行信号合成,得到中频数字位置监视信号、中频数字宽度监视信号以及中频数字余隙监视信号;对中频数字位置监视信号、中频数字宽度监视信号以及中频数字余隙监视信号进行上变频处理,得到对应的三路射频模拟监视信号。通过采用上述方法,解决传统的仪表着陆系统中监视信号合成单元的输出信号不能真实反映监视信号合成单元的实际输入,且监视器检测到的指标并不能真实反映天线辐射信号的实际情况的问题。
