Abstract
The present disclosure provides a wireless performance testing method and system based on quiet zone expansion in a compact antenna test range. The wireless performance testing method is implemented based on a wireless performance testing device and includes: to acquire an original phase of the feed antenna; rotate the turntable to obtain a first scattering parameter of the device under test; input the first distance to a phase compensation model to obtain a compensation phase; adjust the original phase of the feed antenna to the adjusted phase; rotate the turntable to obtain a second scattering parameter of the device under test; move the feed antenna along the first straight line repeatedly to different positions to obtain a plurality of the second scattering parameters. The wireless performance testing method can increase the size of the test quiet zone under the condition that the reflecting surface size is certain.
