| Abstract: | 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. |
