(EN) GLOBAL NEAREST NEIGHBOR (GNN) BASED TARGET TRACKING AND DATA ASSOCIATION
(FR) SUIVI DE CIBLE BASÉ SUR LE VOISIN LE PLUS PROCHE GLOBAL (GNN) ET ASSOCIATION DE DONNÉES
Abstract
(EN)
A modified GNN/DA subsystem processes angle only measurements from at least two sensors (but can be replicated to n sensors using a similar track fusion framework per sensor as a local track center and then fusing them via a multiple local track fusion architecture) to reconstruct a complete battle space picture consisting of multiple moving targets. In some cases, the sensor is an EO/IR camera and the moving targets are UAVs. The modified GNN/DA is used as part of a Fire Control Solution (FCS) either implemented on a ground-based vehicle or on-board a projectile.
(FR)
L'invention concerne un sous-système de GNN/DA modifié qui ne traite des mesures d'angle qu'à partir d'au moins deux capteurs (mais qui peut être répliqué sur n capteurs à l'aide d'un cadre de fusion de trajectoires similaires par capteur en tant que centre de trajectoire locale, et puis par leur fusion par le biais d'une architecture de fusion de trajectoires locales multiples) pour reconstruire une image d'espace de bataille complète constituée de multiples cibles mobiles. Dans certains cas, le capteur est une caméra EO/IR et les cibles mobiles sont des UAV. Le GNN/DA modifié sert de partie d'une solution de lutte contre le feu (FCS) mise en œuvre soit sur un véhicule terrestre soit embarqué sur un projectile.
