摘要： 根据罗兰C导航系统信号的基本特征，以软件无线电理论为指导思想，设计一种罗兰C系统信号模拟器。该模拟器采用通用计算机和现场可编程门阵列(FPGA)芯片构建上位机、下位机架构，基于PCIE进行上下位机通信，模拟产生罗兰C导航系统信号。针对实际信号环境，该模拟器可以模拟多台链信号、天波信号、单频干扰、噪声干扰等信号场景。该模拟器可应用于罗兰C信号特征研究及接收设备的维修检测等。

关键词: 罗兰C, 导航系统, 信号模拟器, 现场可编程门阵列

Abstract: According to the basic characteristics of Loran-C navigation system signal,based on SDR(Software Defined Radio) theory,a kind of signal simulator of Loran-C navigation system is designed.Building the architecture of the upper system and the lower system with General-purpose computer and FPGA chip,and using PCIE bus as the information communication media,the signal simulator can produce sky-wave signal,the station chain and the band interference signal and the noise jamming signal.The simulator can be applied to the research of Loran-C signal characteristics and the maintenance of receiving equipment.

Key words: Loran-C, Navigation system, Signal simulator, FPGA(Field Programmable Gate Array)
