Abstract
The invention relates to a method for determining calibration data, for a goniometry apparatus comprising an antenna array, from several sets of calibration data. The sets are associated with a measured angular position and include an amplitude datum and a phase datum measured by each antenna. The method includes calculating an estimated calibration data set and normalizing the data set measured by providing as many normalized data sets as there are antennas for each measured position. The method includes calculating a candidate data set by interpolating the measured data sets at the measured positions and previously normalized with respect to the phase measured by the antenna, and selecting the candidate data set whose phase reference has the highest energy. The invention relates to a computer program and an apparatus implementing the method, a calibration table obtained by the method and a goniometry apparatus calibrated with the method.
