Claim 2:
3. The method according to either claim 1, comprising a step wherein the roll-call acquisition of a target is ensured as soon as it enters into the interrogation coverage of said radar by exploiting:
the position coded in the ADS-B squitters transmitted by said target, as soon as it enters into a reception coverage of said radar;
the roll-call identity of said target, which is contained in its Mode S address, which is coded in said squitters,, a single roll-call interrogation being transmitted every N rotations of the antenna in order to lock the target to the code of the radar station and thus to avoid pollution by the DF11 replies that a target usually generates on each rotation, potentially as soon as it enters into said interrogation coverage and up to a region of operational range of said radar.
