Zusammenfassung:	A distance measurement method and apparatus. The method comprises: obtaining first measurement information and second measurement information (S410), the first measurement information comprising multiple sets of sampling data obtained by sampling retroreflection measurement signals which are received by a first device by means of multiple antenna channels of a single antenna, and the second measurement information comprising multiple sets of sampling data obtained by acquiring measurement signals which are received by a second device by means of multiple antenna channels of each of multiple antennas; and determining a distance between the first device and the second device according to the first measurement information and the second measurement information (S420). According to the method, distance measurement is performed on the basis of multi-antenna switching frequency hopping, such that the distance measurement relay meets a requirement, and the accuracy and robustness of distance measurement are also imp
