高精度VOR/ILS航空导航信号发生技术

High Precision VOR/ILS Aviation Navigation Signal Generation

该文介绍了仪表着陆系统(Instrument Landing System,ILS)和甚高频全向信标(Very High Frequency Omni directional Range,VOR)的航空导航系统中重要性,以及应用中的工作原理。通过设计原理进行方案设计,提出一种基于FPGA的地面信号发生技术,具有资源利用率高、配置灵活高效等特点,能够产生高精度LOC、GS、MB和VOR基带信号。最后进行了仿真实验,得到各种基带信号的波形图,验证了该技术的可靠和有效。

In this paper,we have introduced the impotance of Instrument Landing System （ILS） and Very HighFrequency Omnidirectional Range（VOR） in the air navigation system,and the operation principle in the application.Have designed a scheme on the basis of the principle design,and then we put forward a kind of groundsignal generation technology based on FPGA.It has the characteristics of high utilization rate of resources andflexible and efficient allocation,and can generate high precision LOC,GS,MB and VOR baseband signals.Finally,the simulation experiment is carried out to obtain the waveform of various baseband signals,which proves thatthe technology is reliable and effective.
