Claim 0:
1. A measurement method implemented by an over-the-air measurement system, and comprising:
determining, for each antenna group other than a target antenna group in an antenna array, a plurality of compensation values of the antenna group based on a first set of characteristic parameters of the antenna group and a second set of characteristic parameters of the target antenna group, wherein the first set comprises a first characteristic parameter for determining a first phase compensation value and a second characteristic parameter for determining a first amplitude compensation value, wherein the second set comprises a third characteristic parameter for determining a second phase compensation value and a fourth characteristic parameter for determining a second amplitude compensation value, wherein the compensation values comprise a third phase compensation value and a third amplitude compensation value;
using an azimuth and a pitch angle between a normal line of a measurement probe of an over-the-air measurement system and a connection line between a first center point of the antenna group and a second center point of the measurement probe as the second characteristic parameter;
obtaining a first gain decrement of the antenna group based on an azimuth corresponding to the antenna group;
obtaining a second gain decrement of the measurement probe based on the pitch angle;
using a sum of the first gain decrement and the second gain decrement as the first amplitude compensation value; and
adjusting a first electromagnetic wave from each antenna unit in the antenna group based on the compensation values,
wherein the first electromagnetic wave has a same phase or a same amplitude as a plurality of electromagnetic waves from all antenna units in the antenna array when the first electromagnetic wave arrives at the measurement probe, and
wherein the first electromagnetic wave is for measuring an over-the-air beam parameter of a first device of the over-the-air measurement system.
