Title (EN) OPTICAL AIR DATA SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE DONNÉES AÉRIENNES OPTIQUES
Abstract:
(EN) An optical air data system for an air vehicle includes a LIDAR module and a data processing module. The LIDAR module is configured to emit at least three laser beams, not all located in a common plane, and perform LIDAR measurements of a backscattered component of each of the laser beams. The data processing module includes a processor and machine-readable instructions that, when executed by the processor, processes the LIDAR measurements to determine at least one optically-based air data parameter. The overlap between the laser beams and one or more fields of view of the LIDAR module may be within two meters from the LIDAR module to determine the at least one optically-based air data parameter at short range from the air vehicle.
(FR) La présente invention concerne un système de données aériennes optiques pour un véhicule aérien qui comprend un module LIDAR et un module de traitement de données. Le module LIDAR est configuré pour émettre au moins trois faisceaux laser, qui ne sont pas tous situés dans un plan commun, et effectuer des mesures LIDAR d’une composante rétrodiffusée de chacun des faisceaux laser. Le module de traitement de données comprend un processeur et des instructions lisibles par machine qui, lorsqu’elles sont exécutées par le processeur, traite les mesures de LIDAR pour déterminer au moins un paramètre de données aériennes à base optique. Le chevauchement entre les faisceaux laser et un ou plusieurs champs de vision du module LIDAR peut être compris entre deux mètres à partir du module LIDAR afin de déterminer l’au moins un paramètre de données aériennes à base optique à courte distance du véhicule aérien.
