Title
(EN) SYSTEM AND METHOD FOR DRONE AND OBJECT CLASSIFICATION
(FR) SYSTÈME ET PROCÉDÉ POUR LA CLASSIFICATION DE DRONES ET D'OBJETS
Abstract
(EN)
A method and system device provides a unique object identification process by obtaining information from one or more of radar signals, infrared signals, optical signals, audio signals, and other signals. The method includes continuously receiving object data at the device, applying by a machine learning system, a set of parameters to process the object identification and confidence level, and outputting or updating the object identification, confidence level, and actionable recommendations. The radar data includes a Doppler signature having a wrapped signal due to a sampling rate of the radar system. The Doppler signature is used to train the machine learning system to identify drone types.
(FR)
L'invention concerne un dispositif de procédé et de système fournissant un processus d'identification d'objet unique par obtention d'informations à partir d'un ou de plusieurs signaux radar, signaux infrarouges, signaux optiques, signaux audio et autres signaux. Le procédé consiste à recevoir en continu des données d'objet au niveau du dispositif, à appliquer, au moyen d'un système d'apprentissage automatique, un ensemble de paramètres pour traiter l'identification d'objet et le niveau de confiance, et à émettre ou à mettre à jour l'identification d'objet, le niveau de confiance et les recommandations exploitables. Les données radar comprennent une signature Doppler ayant un signal enveloppé en raison d'un taux d'échantillonnage du système radar. La signature Doppler est utilisée pour entraîner le système d'apprentissage automatique à identifier des types de drones.
