Calibration process
The probe array system calibration allows for both
consistency in amplitude and in phase as well as the
radio-electric axis alignment of each probe. The calibration
procedure consists of the rotation of a reference antenna
along a roll axis in front of each probe. This is performed
with a dedicated calibration arm supporting the reference
antenna and its motorized roll axis. Mounted on one of
the linear axes of the scanner, the calibration arm moves
linearly to position the reference antenna in front of each
probe of the array.
