This invention is an easily deployable, expendable or recoverable floating radar reflective device. The invention can be built with sufficient reserve buoyancy to allow the fitting of a number of optional devices, such as a GPS transceiver or lighting. Thus, the device can be used for a variety of applications including: man- overboard marker, radar testing, temporarily marking submerged objects or navigation points, search and rescue, naval gunnery practice and/or weapons testing, or any other application that requires a floating reflective station. The device is constructed of aluminum, and consists of an internally supported tetrahedron shape with a floatation pod with an integrated radar reflector at each apex. The tetrahedron shape allows the device to roll due to the motion of the waves or the method of deployment, and always present the same shape and reflective area as a target for radar, or as a support for optional devices mounted on the structure. Each floatation pod is fitted either with scuttling devices, to cause the device to sink if recovery is not a preferred option, or plugs if recovery is required. The use of dissimilar metal in the scuttling devices and the pins that hold the device together allows the device to rapidly corrode once it sinks, alleviating environmental concerns. The device is collapsible for ease of storage, and can be either assembled by hand, or deployed automatically, depending upon usage requirements.
Cette invention est un dispositif flottant réfléchissant au radar, facile à déployer, remplaçable ou récupérable. L'invention peut être construite avec une réserve de flottabilité suffisante pour permettre la pose d'un certain nombre de dispositifs optionnels, tels qu'un émetteur/récepteur GPS ou un éclairage. Ainsi, le dispositif peut être utilisé pour une variété d'applications, notamment : marqueur d'homme à la mer, tests du radar, marquage d'objets temporairement submergés ou de points de navigation, recherche et sauvetage, entraînement d'artillerie navale et/ou essais d'armes, ou toute autre application nécessitant une station flottante réfléchissante. Le dispositif est construit en aluminium et se compose d'une forme de tétraèdre supportée en interne avec une nacelle de flottaison équipée d'un réflecteur radar intégré à chaque sommet. La forme de tétraèdre permet au dispositif de rouler en raison du mouvement des vagues ou de la méthode de déploiement et de toujours présenter la même forme et la même aire réfléchissante comme cible pour le radar, ou comme support pour les périphériques en option montés sur la structure. Chaque nacelle de flottaison est équipée soit de dispositifs de sabordage pour faire couler le dispositif si la récupération n'est pas une option privilégiée, soit de bouchons si la récupération est nécessaire. L'utilisation de métaux dissemblables dans les dispositifs de sabordage et les chevilles qui assemblent le dispositif permet au dispositif de s'éroder rapidement une fois coulé, atténuant ainsi les préoccupations environnementales. Le dispositif est démontable pour faciliter le stockage, et peut être soit assemblé à la main, soit déployé automatiquement, selon les conditions d'utilisation.
