Abstract
A method for determining a phase bias in the signal transmitted by at least one of the radiating elements of an active antenna on the ground emitting signals into space using a space-division multiple access SDMA method, implementing a step, for each reference receiver, of comparing, to a threshold, the difference between the value of a measurement of the power received by each reference receiver and the sum, out of the radiating elements of the subset beamforming in the direction of the reference receiver, of the differences between the equivalent isotropically radiated power in the direction of the reference receiver and the free-space path loss of each radiating element of the subset.
