(EN) ESTABLISHING LINE-OF-SIGHT BETWEEN DRONE AND TARGET
(FR) ÉTABLISSEMENT D'UNE LIGNE DE VISÉE ENTRE UN DRONE ET UNE CIBLE
Abstract
(EN)
In this invention we have a drone consisting of a radar trying to hit a target in its airspace. Here the drone has the capability of adapting on its own to different positions to establish line-of-sight with the target. The above is possible because the drone consists of a monostatic radar receiver that processes pulses of radio waves that propagate through objects that are obstacles like penetrable walls or layers of ground and these pulses of radio waves could have been reflected back through other objects in an obscuration channel. This helps the drone in real time to adapt to different positions to establish line-of-sight with different targets in an obscuration channel.

Dans la présente invention, un drone constitué d'un radar essayant de frapper une cible dans son espace aérien. Le drone possède la capacité de s'adapter lui-même à différentes positions pour établir une ligne de visée avec la cible. Ce qui précède est rendu possible car le drone est constitué d'un récepteur radar monostatique qui traite des impulsions d'ondes radio qui se propagent à travers des objets qui sont des obstacles tels que des murs ou des couches de sol pénétrables et ces impulsions d'ondes radio pourraient avoir été réfléchies à travers d'autres objets dans un canal d'obscurcissement. Ceci aide le drone en temps réel à s'adapter à différentes positions pour établir une ligne de visée avec différentes cibles dans un canal d'obscurcissement.
