Title:
PHASE COMPENSATION METHOD AND DEVICE FOR MEASURING ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/214259
Kind Code:
A1
Abstract:
Provided are a phase compensation method and device for measuring an array antenna, the phase compensation method comprising: step S1, exporting measured far-field patterns of a first array unit and a second array unit to establish a coordinate system so as to determine a spatial-geometric relationship between the first array unit and the second array unit; step S2, determining a wave path difference between the first array unit and the second array unit according to the spatial-geometric relationship between the first array unit and the second array unit; and step S3, performing phase compensation on the second array unit according to the wave path difference. According to the invention, after phase compensation and port zeroing, each array unit can avoid additionally introducing a beam pointing error so as to improve the testing precision regarding the electrical properties of a radome.
