Title:
MEASURING ANTENNA ARRAY BEAM SYNTHESIS METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/214258
Kind Code:
A1
Abstract:
A measuring antenna array beam synthesis method, the method comprising: acquiring the phase, amplitude, and related distance values of each antenna unit, the related distance values comprising a first distance value and a second distance value, the first distance value being information of the distance between each antenna unit and a turntable centre and the second distance value being information of the distance between each antenna unit and the adjacent antenna unit (S101); calculating a phase directivity pattern of each antenna unit and, on the basis of the phase and first distance value of each antenna unit, compensating the phase directivity pattern of each antenna unit in order to obtain the phase error value of each antenna unit (S103); and, on the basis of the phase, amplitude, second distance value, and phase error value of each antenna unit, synthesising the radio frequency signals of the plurality of antenna units in order to obtain an antenna beam (S105). By means of implementing beam synthesis on far field data tested by a single antenna, the present method can implement equivalent testing of directivity patterns with a transmitter.
