摘　　要：本文对仪表着陆与全向信标分析仪中航向信标信号基于FPGA的数字中频处理技术进行了研究,提出了一种基于数据分离滤波的数字中频处理方案。与传统的数字中频处理方案相比,对LOC多频调制信号进行了分离测量,提高了测试的精度,对仪表着陆与全向信标分析仪广泛应用于机场校飞、日常监测和设备维护有着重要的意义。In this paper,the digital IF processing technology of heading beacon signal in instrument landing and omni-directional beacon analyzer based on FPGA is studied,and a digital IF processing scheme based on data separation and filtering is proposed.Compared with the traditional digital IF processing scheme,the LOC multi frequency modulation signal is separated and measured,which improves the test accuracy.It is of great significance for the instrument landing and omni-directional beacon analyzer to be widely used in airport flight calibration,daily monitoring and equipment maintenance.
