METHOD FOR DETERMINING A PASSIVE PATHOGRAPHY OF A MOBILE SOURCE BY A REVERSE TRIANGULATION METHOD

摘要

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