Abstract
Le dispositif comporte au moins : - des moyens d'émission de signaux hyperfréquence ; - des moyens de réception de signaux réfléchis par une cible , ; - des moyens de calcul ; - une pluralité de systèmes d'antennes (22) disposés autour de l'aéronef, un système d'antennes comportant un ensemble d'antennes d'émission (31, 32, 34) couplées au moyens d'émission et un ensemble d'antennes de réception (30) couplées aux moyens de réception, chaque système d'antenne (22) étant dédié à la couverture d'un secteur angulaire donné Ω ; pour un système d'antenne donné, le faisceau d'antenne à la réception étant formé par FFC par les moyens de calcul à partir des signaux reçus par les antennes de réception (30) et le faisceau d'antenne à l'émission est pointé par un système à balayage électronique dans un nombre supérieur ou égal à deux de directions à l'intérieur du secteur angulaire donné Ω . L'invention s'applique notamment dans le domaine des radars aéroportés, en particulier les radars à grande couverture angulaire et à courte portée nécessaires par exemple pour réaliser une fonction du type « voir et éviter » sur des drones, fonction encore communément appelée « Sense & Avoid ».The device comprises at least: - means for transmitting microwave signals; - means for receiving signals reflected by a target,; - means of calculation; - a plurality of antenna systems (22) arranged around the aircraft, an antenna system comprising a set of transmitting antennas (31, 32, 34) coupled to the transmitting means and a set of reception antennas (30) coupled to the reception means, each antenna system (22) being dedicated to the coverage of a given angular sector Ω; for a given antenna system, the antenna beam on reception being formed by FFC by the calculation means from the signals received by the reception antennas (30) and the antenna beam on transmission is pointed by an electronic scanning system in a number greater than or equal to two of directions within the given angular sector Ω. The invention applies in particular to the field of airborne radars, in particular radars with large angular coverage and short range necessary for example to perform a function of the “see and avoid” type on drones, a function also commonly called “Sense”. & Avoid ”.
