Abstract
A measurement method for a device includes, for each antenna group other than a target antenna group in an antenna array, determining compensation values of the antenna group based on characteristic parameters of the antenna group and characteristic parameters of the target antenna group, and adjusting, based on the compensation values of the antenna group, an electromagnetic wave transmitted by each antenna unit in the antenna group such that electromagnetic waves transmitted by all antenna units in the antenna array have a same phase or amplitude when the electromagnetic waves arrive at a measurement probe of a second device, where the electromagnetic wave is used to measure an over-the-air beam parameter of the first device, and a distance between the first device and the measurement probe is less than a far-field boundary distance.
