摘 要： 给出了一种仪表着陆系统（ILS）实训平台的设备改造方案，应用实际设备改造，对调制后的射频信号衰减后进行功率和相位的分配，然后溃入天线监控混合网络，合理构造出从每个发射天线耦合回来的监控信号。在没有向空间发送射频信号的情况下，在实验室中搭建完整的实训平台。该实训平台的发射系统、发射信号及其流程、监控信号及监控过程与真实设备完全一样，为业务培训提供了真实的环境。以NM7000B型仪表着陆系统航向信标设备为例进行改造，该方案在实验室真实设备上进行验证，结果证明了方案的可行性。

Abstract： The reforming scheme for training platform equipment of instrument landing system （ILS） is proposed. The power and phase of the modulated RF signal after attenuation are distributed by application of the actual equipment reforming， and the signal is fed into the antenna to monitor the mixed network. The monitoring signal coupled back from each transmitting antenna was constructed reasonably. The integrated training platform was built in the laboratory under the condition that the RF signal isn’t transmitted to the space. The transmitting system， transmitting signal and its process， monitoring signal and monitoring process of this training platform are exactly the same with the true equipment， which provides the true environment for operation training. The localizer equipment of NM7000B ILS as an instance was reformed. The...
