Abstract: This application provides a radar signal processing method and apparatus, which are applicable to the waveform design of a millimeter-wave radar. The radar signal processing method is applicable to an apparatus, for example, a millimeter-wave radar or a chip system inside the millimeter-wave radar, and the method includes: transmitting a first radar signal on a first frequency band; transmitting a second radar signal on a second frequency band; receiving a first reflected signal and a second reflected signal, where the first reflected signal is an electromagnetic wave reflected by a target object in response to the first radar signal, and the second reflected signal is an electromagnetic wave reflected by the target object in response to the second radar signal; and obtaining at least one of range information, velocity information, and angle information of the target object.

Abstract: A detection method includes determining a first frequency point of N frequency points, transmitting a radio signal in a first frequency band in N frequency bands. One of the N frequency bands partially overlaps at least one frequency band in other N−1 frequency bands, and an absolute value of a difference between lowest frequencies of any two frequency bands of the N frequency bands is not less than a first threshold (F), or the N frequency bands have at least one second frequency band that partially overlaps the first frequency band, and an absolute value of a difference between a lowest frequency of each second frequency band and a lowest frequency of the first frequency band is not less than F.

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.
