Claim 0:
1. A method for locating, with a secondary radar comprising an antenna having a radiation pattern forming a sum channel, designated SUM, a radiation pattern forming a difference channel, designated DIFF, and a pattern forming a control channel, designated CONT, targets transmitting ADS-B squitters, the secondary radar having a predefined interrogation coverage, wherein said targets are located by implementing the following steps:
detecting ADS-B squitters received via said CONT channel, via said SUM channel and via said DIFF channel;
measuring at least the power of said squitters and their azimuth with respect to said radar;, the location of a target transmitting ADS-B squitters being computed by exploiting at least the detection of a single ADS-B squitter, in light of the latitudinal and longitudinal position of said radar and of the azimuthal measurement with respect to said radar, a position cell, designated the CPR cell, coded in said squitter being selected via said azimuthal measurement.
