Title
(EN) MULTIPOLARIZED VECTOR SENSOR ARRAY ANTENNA SYSTEM FOR SEARCH AND RESCUE APPLICATIONS
(FR) SYSTÈME D'ANTENNE À RÉSEAU DE CAPTEURS DE VECTEUR MULTIPOLARISÉ POUR APPLICATION DE RECHERCHE ET DE SAUVETAGE
Abstract
(EN)
The present disclosure is directed towards direction finding (DF) systems that can detect and locate a radio frequency (RF) signal (e.g. an emergency beacon) in two dimensions (i.e., azimuth and elevation). In one embodiment, a DF system comprises an array of multipolarized loop antennas coupled to a beamformer which provides monopole, dipole, and loop antenna element modal signals. The DF system may also comprise a multi-channel digital receiver system coupled to the beamformer. The multi-channel digital receiver system is configured to receive modal signals provided thereto from the beamformer which can be used for accurate two-dimensional geolocation of RF signals including, but not limited to, location of RF emergency beacon sources.
(FR)
La présente invention concerne des systèmes radiogoniométriques (DF) aptes à détecter et localiser un signal radiofréquence (RF) (par ex. une balise d'urgence) dans deux dimensions (azimut et altitude). Dans un mode de réalisation, un système DF comprend un réseau d'antennes cadre multipolarisées couplé à un module de formation de faisceau qui fournit des signaux modaux d'éléments d'antenne monopôle, dipôle et cadre. Le système DF peut également comprendre un système récepteur numérique multi-canal couplé au module de formation de faisceau. Le système récepteur numérique multi-canal est configuré pour recevoir des signaux modaux, du module de formation de faisceau. Les signaux modaux peuvent être utilisés pour une géolocalisation précise en deux dimensions de signaux RF comprenant, entre autres, l'emplacement de sources de balise d'urgence RF.
