The invention discloses an instrument landing course beacon system capable of resisting multipath interference, and relates to the technical field of air traffic management. The system comprises a signal generation module used for generating a radio frequency signal; the channel signal module and the clearance signal module are used for processing and decomposing the radio frequency signal to obtain a channel correction signal and a clearance correction signal; the signal output module is used for correcting and outputting original channel signals and clearance signals based on the channel correction signals and the clearance correction signals, and the feedback module is used for sampling output signals of the signal output module and comparing the output signals with radio frequency signals to obtain error values. According to the invention, high-precision control and adjustment of the radio frequency signal can be realized, independent and rapid adjustment of the beam shape is realized, the anti-multipath interference capability of the instrument landing system is improved, and the operation efficiency of an airport is improved.
