<p>Method and apparatus for locating sources (P1,P2) emitting radio signals comprising a plurality of passive antennae (R11,R12,R21,R22,R30) arranged at different locations (S1,S2,S3), having
- at least two pairs (R10,R20) of receiving antennae which are positioned in at least two different locations (S1,S2) situated ata suitable distance (D1) from each other;
- at least one additional receiving antenna (R30) arranged at a third location (S3) situated at a suitable distance (D2,D3) from each one of the two said first locations (S1,S2);
- devices for digitally processing the signals, mounted on each of said antennae and able to generate, for each signal received, a digital report containing at least the time of arrival (TOA) of the signal at the respective antenna;
- a synchronization sysem able to supply a synchrnoizing signal to all the antennae;
- a centralized date procesisng unit (E) able to process the information contained in the said reports received from the respective antennae;
- a communications system which connects each antenna to the processing unit for tranmission of the respective reports.</p> |
