Flip test procedure for positioning system errors and antenna phase centre determinations

The pattern phase centre is determined using measurements in a specific cut plane. This parameter is totally defined by a lateral and a longitudinal distance which are specified in the measured cutting plane. These lengths determinations can be corrupted by two elements: misalignment of the antenna under test and positioning systems errors. To solve the whole problem, a procedure based on flip tests is applied. After a presentation of the problem to solve, the flip test procedure is explained and applied to measurements performed in both Ka- and V-band.
