A method for locating in space, by 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 at least the following steps: ∘ step 1: determining a first monopulse angle Ψ Rx H A S, Ψ Rx B A S, so as to define a first response acceptance zone ZAR 1, by a measurement on the signal emitted by the target and received on an antenna array comprising at least two individual antennas and taken from one of said first or second antenna array (ARRAY_H, ARRAY_B), the first monopulse angle being determined from a first sum signal obtained by combining the received signals on all the antenna elements of said antenna array and from a second difference signal obtained by combining the signals received on all the antenna elements of said antenna array, ∘ step 2: creating a third combined linear antenna array (ARRAY_C) by coupling at least one individual antenna of the first antenna array (ARRAY_H) and at least one individual antenna of the second antenna array (ARRAY_B), the third combined antenna array (ARRAY_C) having a different axis than the axis of the first antenna array (ARRAY_H) and the axis of the second antenna array (ARRAY_B). ∘ step 3: determining a second monopulse angle Ψ Rx C A S, so as to define a second response acceptance zone ZAR 2, by a measurement on the signal emitted by the target and received on the third combined antenna array (ARRAY_C), said zone being formed by one or more windows in the plane (A, S), the second monopulse angle being determined from a first sum signal obtained combining the signals received on all the antenna elements of the third combined antenna array and from a second difference signal obtained by combining the received signals on all the antenna elements of the third combined antenna array;

∘ step 5: forming a fourth response acceptance zone ZAR 4 by eliminating the secondary windows from the second response acceptance zone ZAR 2 by comparison of the signal level received on the first antenna array (ARRAY_H) with that received on the second antenna array (ARRAY_B) via an amplitude discrimination method. ∘ step 1: determining a first monopulse angle Ψ Rx H A S, Ψ Rx B A S, so as to define a first response acceptance zone ZAR 1, by a measurement on the signal emitted by the target and received on an antenna array comprising at least two individual antennas and taken from one of said first or second antenna array (ARRAY_H, ARRAY_B), the first monopulse angle being determined from a first sum signal obtained by combining the received signals on all the antenna elements of said antenna array and from a second difference signal obtained by combining the signals received on all the antenna elements of said antenna array, ∘ step 2: creating a third combined linear antenna array (ARRAY_C) by coupling at least one individual antenna of the first antenna array (ARRAY_H) and at least one individual antenna of the second antenna array (ARRAY_B), the third combined antenna array (ARRAY_C) having a different axis than the axis of the first antenna array (ARRAY_H) and the axis of the second antenna array (ARRAY_B). ∘ step 3: determining a second monopulse angle Ψ Rx C A S, so as to define a second response acceptance zone ZAR 2, by a measurement on the signal emitted by the target and received on the third combined antenna array (ARRAY_C), said zone being formed by one or more windows in the plane (A, S), the second monopulse angle being determined from a first sum signal obtained combining the signals received on all the antenna elements of the third combined antenna array and from a second difference signal obtained by combining the received signals on all the antenna elements of the third combined antenna array;
