INTERFERENCE DETECTION METHOD AND DEVICE

This application provides an interference detection method and apparatus, and belongs to the field of radar technologies. The method includes: obtaining a digital signal obtained by processing a radar echo signal; processing the digital signal via at least two filters with different cut-off frequencies to obtain at least two filtered signals; and determining, based on each of the at least two filtered signals and an interference detection threshold corresponding to each filtered signal, whether an interference signal exists in the radar echo signal. In embodiments of this application, the at least two filters with different cut-off frequencies filter the digital signal, to separately perform interference detection on each filtered signal to implement interference detection on the radar echo signal. This improves interference detection precision. Further, the method improves an advanced driver assistance system ADAS capability of a terminal during autonomous driving or assisted driving, and may be applied to the Internet of vehicles, for example, vehicle-to-everything V2X, long term evolution-vehicle LTE-V, and vehicle-to-vehicle V2V.
