Title:
NEAR-FIELD AIR INTERFACE RAPID MEASUREMENT SYSTEM AND METHOD FOR PATTERN OF ACTIVE ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2024/045649
Kind Code:
A1
Abstract:
A near-field air interface rapid measurement system and method for a pattern of an active array antenna, which is used for increasing the measurement speed of the pattern of the active array antenna, can shorten the measurement distance, and can complete measurement of the pattern of the active array antenna when no turntable is required and the position of a probe is fixed. The measurement system comprises a mechanical adjustment device, an amplitude-phase measurement subsystem, a control subsystem, and a probe antenna (1). The measurement method comprises: determining the placement position of the probe antenna (1) according to array plane parameters; dividing unit antennas in an array into a certain number of antenna groups according to the array plane parameters and the position of a probe; establishing an amplitude-phase state table to be measured for the antenna groups according to a beam group to be measured, and merging repeated states; performing measurement to obtain an actually measured amplitude-phase excitation table; according to simulated and actually measured patterns of the antenna groups, calculating a normalized amplitude-phase excitation table of the antenna groups from the actually measured amplitude-phase excitation table; and calculating a pattern of a beam to be measured of the array according to the simulated and actually measured patterns of the antenna groups and the normalized amplitude-phase excitation table of the antenna groups.
