METHOD OF DETERMINING A TRAJECTORY MAPPING BY PASSIVE PATHWAY OF A MOBILE SOURCE BY A METHOD OF INVERSE TRIANGULATION
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 a...

Summary: | 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).
Le procédé d'estimation de la trajectoire d'une source mobile (SM) dans un plan de l'espace par voie passive, la source mobile (SM) générant au moins un premier signal (S1) et un second signal (S2) se propageant respectivement à deux vitesses différentes, comprend : une acquisition des signaux (S1, S2) par au moins une antenne (ANT1, ANT2); une estimation d'angles (DET1) d'au moins quatre angles d'arrivée (θ1, θ2, θ3, θ4) dont au moins un angle (θ1) correspond à une mesure de l'angle d'arrivée du premier signal (S1), et dont au moins au moins un angle (θ2) correspond à une mesure de l'angle d'arrivée du second signal (S2) par au moins une antenne (ANT1, ANT2); une estimation d'une position et d'un vecteur vitesse (VSM) de la source mobile (SM) à un instant donné (ti). |
