1. A signal processing method, wherein the method comprises:
performing channel listening based on a first signal and a second signal, wherein the channel listening comprises performing channel listening based on a first listening signal in a first time domain range in time domain and performing channel listening based on a second listening signal in a second time domain range in time domain; and
determining, based on a result of the channel listening, a first time-frequency resource for target detection, wherein a time domain resource of the first time-frequency resource is the first time domain range;
the first time domain range and the second time domain range are time domain ranges in L time domain ranges; L is a positive integer greater than 1; any one of the L time domain ranges partially overlaps at least one of other (L−1) time domain ranges; and an absolute value of a difference between time domain start locations of any two of the L time domain ranges is greater than or equal to a first threshold and less than or equal to a second threshold, wherein the first threshold and the second threshold are predefined or determined according to a preconfigured rule based on at least one of an echo delay or a propagation delay; and
the first listening signal corresponds to a first sub-signal that is of the first signal and that is in at least one first frequency sweep period in the first time domain range, and the second listening signal corresponds to a second sub-signal that is of the second signal and that is in at least one second frequency sweep period in the second time domain range.
