Abstract:
1. A method for locating in space, from a carrier, a target of azimuth A estimated target and of elevation angle S estimated target using at least one first linear antenna array with electronic scanning ARRAY_H comprising at least one individual antenna and at least one second linear antenna array with electronic scanning ARRAY_B comprising at least two individual antennas, said target emitting a signal in response to an interrogation from the carrier, the method comprising: step 1: creating a third combined linear antenna array ARRAY_C by coupling at least one individual antenna of the antenna array ARRAY_H and at least one individual antenna of the antenna array ARRAY_B, step 2: determining the monopulse angle Ψ step 3: determining the monopulse angle Ψ step 4: forming, from at least the information items Ψ
