The invention relates to a method and system for the testing of an antenna comprising a plurality of radiating elements, wherein an array of one or more probes is placed in front of the antenna to be tested, and wherein the following steps are performed: acquisition by the array of one or more probes or by the radiating elements of the antenna under test of an RF signal emitted by the antenna under test or by the array of one or more probe (s), back propagation reconstruction of the signal emitted through a computation of the signal received by the various probes of the array of one or more probes or by the radiating elements of the antenna under test, test of the signal thus reconstructed or of parameters thereof to detect a potential defect of the antenna.
