Abstract: A ranging method and apparatus are provided. The method includes: obtaining first measurement information and second measurement information (S410), where the first measurement information includes a plurality of groups of sampled data that are obtained by a first device by sampling retroreflection measurement signals received through a plurality of antenna channels of a single antenna, and the second measurement information includes a plurality of groups of sampled data that are obtained by a second device by sampling measurement signals received through a plurality of antenna channels of each of a plurality of antennas; and determining a distance between the first device and the second device based on the first measurement information and the second measurement information (S420). In this method, ranging is performed based on multi-antenna switching frequency hopping, so that a ranging delay meets a requirement, and ranging precision and robustness are improved.
