Abstract (en)

[origin: WO2016087661A1] The method of estimating the trajectory of a mobile source (SM) in a plane in space by passive pathway, the mobile source (SM) generating at least one first signal (S1) and one second signal (S2) propagating respectively at two different speeds, comprises: an acquisition of the signals (S1, S2) by at least one antenna (ANT1, ANT2); an estimation of angles (DET1) of at least four angles of arrival (θ1, θ2, θ3, θ4) of which at least one angle (θ1) corresponds to a measurement of the angle of arrival of the first signal (S1), and of which at least one angle (θ2) corresponds to a measurement of the angle of arrival of the second signal (S2) by at least one antenna (ANT1, ANT2); an estimation of a position and of a speed vector (VSM) of the mobile source (SM) at a given instant (ti).
