摘要/Abstract

摘要： 在分析仪表着陆系统ILS(Instrument Landing System)下滑调制深度差DDM(Different in the Depth of Modulation)指标形成原理的基础上,找到了影响DDM的因素为纯边带SBO(Sideband Only)信号的幅值,采用控制变量法得出了在DDM线性变化范围内SBO信号的幅值与下滑宽度、半宽度的关系模型,并通过实测数据对模型进行了验证。基于数学模型并结合NM7000设备,搭建了仿真系统,可动态模拟下滑宽度的调整过程。测试结果表明,仿真系统精度相对误差小于1%。系统应用对指导校飞及设备维护具有重要意义。

Abstract: Based on the principle of the formation of the instrumental landing system ILS(Instrument Landing System) gliding DDM(Different in the Depth of Modulation) index, and the factors that affect DDM are found as the amplitude of SBO(Sideband Only) signal. The relationmodel between the amplitude and the glide width, of the Half-width SBO signal in the linear variation range of DDM are obtained by the control variable method. And Based on the measured data, the correctness of the model is verified. Based on the mathematical model and combined with the NM7000 equipment, a simulation system is built to dynamically simulate the adjustment process of the slide width. The test results show that the system error is less than 1%. System applications are important for the guiding calibration flight and the equipment maintenance.

Key words: glide, control variable method, DDM, glide width, SBO
