An Experience of Elementwise Calibration Methods Without Use of Phase Measurement Apparatus for Multi-Channel PAA Calibration
Författare
Summary, in English
Some known elementwise methods of PAA calibration are considered, without use of phase meas-urement apparatus. Features of these methods are described for the case of multi-channel phased array antennas (several hundreds or thousands of channels). Calibration algorithm is suggested for this case, it consists of antenna channels grouping, in-group channel calibration and, finally, mutual calibration of groups. A method for initial phase distribution creation is suggested, to ensure proper level of common antenna signal. Calibration procedure for the cases of 192-channel and 3600-channel antennas is described.
