摘　　要：针对传统仪表着陆系统(ILS)信号模拟器成本高,智能化程度低,专用化高,通用性差的缺点,设计了一种基于矢量信号发生器的仪表着陆系统模拟器。采用FPGA实现多种调制信号的合成,利用矢量信号发生器的本振信号产生载波,使用矢量信号源的功率调节电路实现输出电平的连续可调,满足并优于模拟器输出信号的要求。本文首先从原理上分析了仪表着陆信号模拟器和矢量信号发生器,然后实现了航向、下滑与指点新标的模拟器,最后给出实际的测试结果,完全满足设计要求和实际应用。In order to overcome the shortcoming of traditional Instrument Landing System(ILS)signal simulator,such as high cost,low intelligence,high customization,low universality,an ILS signal simulator base on VSG is designed.A variety of modulation signals are synthesized and implemented on a FPGA.The carrier signal is synthesized by the local oscillator of a vector signal generator.The output amplitude is continuously tunable because the level control circuits is made full use.All of these methods can satisfy the requirement of signal types requirements.In this paper,the theory of ILS and VSG is firstly analyzed.Then the methods on how to realize the localizer glide slope and marker beacon are achieved.Finally,the testing results are shown and discussed.The results show that the design can full meet the demands of design and actual applications.
