Abstract: A method related to processing interference between cooperative radars, where a radar obtains configuration information used to indicate a ratio of a quantity of first data update periods to a quantity of second data update periods in a sending period. The first data update period is used to send a first radio signal, and the second data update period is used to send a second radio signal. Waveform configurations of the first radio signal and the second radio signal are different, to effectively reduce mutual interference between the first radio signal and the second radio signal.
