摘要
介绍了一种基于FPGA的微波着陆系统信号模拟器,采用基于函数发生器方式设计,由计算机根据微波着陆系统的信号格式计算各种信号数据,将信号数据灵活下载到存储器中,按照要求可产生正常或异常的信号及控制时序。实际测试和应用证明,信号模拟器的性能指标达到设计要求。该方法可应用于多种信号模拟器的设计。
A signal simulator for Microwave Landing System（MLS） based on FPGA is introduced. The simulator is designed using function generator. Based on the MLS signal formats, all kinds of signal data are calculated in advance by computer and then downloaded to ROM flexibly. The normal and abnormal signals are produced in order under the requirements. The test and application results prove that the performance index of signal simulator meets the design requirements. This method can be applied to design many kinds of signal simulator.
