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。
給齣瞭一種儀錶著陸繫統（ILS）實訓平檯的設備改造方案，應用實際設備改造，對調製後的射頻信號衰減後進行功率和相位的分配，然後潰入天線鑑控混閤網絡，閤理構造齣從每箇髮射天線耦閤迴來的鑑控信號。在沒有嚮空間髮送射頻信號的情況下，在實驗室中搭建完整的實訓平檯。該實訓平檯的髮射繫統、髮射信號及其流程、鑑控信號及鑑控過程與真實設備完全一樣，為業務培訓提供瞭真實的環境。以 NM7000B 型儀錶著陸繫統航嚮信標設備為例進行改造，該方案在實驗室真實設備上進行驗證，結果證明瞭方案的可行性。

The reforming scheme for training platform equipment of instrument landing system(ILS)is proposed. The pow?er 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 anten?na 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 pro?cess 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 scheme was verified on the true equipment in the laboratory. The experimental results prove that this scheme is feasible.
