Cluster MTI detection (71) is performed and track pseudomeasurements are generated from de-tected clusters. Existing tracks are then extrapo-lated (73). Measurements are associated (74) with existing group/single tracks. Area visibility is de-termined for miscorrelated tracks (76). Associa-tion and assignment are performed for transitioned tracks (77). Kalman filtering updates are performed (78) on correlated tracks. Existing tracks are man-aged (79). Unassigned measurements are initiated as tentative tracks (80). This process is repeated for each radar revisit.
On effectue une détection (71) de cibles mobiles par groupes et l'on génère des pseudomesures de trajectoires à partir des groupes détectés. Puis on extrapole (73) les trajectoires existantes. On associe (74) des mesures aux trajectoires existantes groupées/individuelles. On détermine la visibilité spatiale pour les trajectoires mal corrélées (76). On effectue une association et une affectation pour les trajectoires ayant subi une transition (77). On effectue des mises à jour (78) du filtrage Kalman sur les trajectoires corrélées. On gère les trajectoires existantes (79). On initialise des trajectoires provisoires (80) avec des mesures non affectées. Puis on répète ce processus pour chaque nouvelle inspection radar.
