Abstract

Un sistema 2 para detectar, clasificar y rastrear vehículos aéreos no tripulados (UAV) 50 que comprende: al menos una matriz de micrófonos 4 dispuesta para proporcionar datos de audio; al menos una cámara 6, 8 dispuesta para proporcionar datos de video; y al menos un procesador 10 dispuesto para generar un mapa de probabilidad de detección espacial que comprende un conjunto de celdas espaciales. El procesador asigna un puntaje de probabilidad a cada celda en función de: una puntuación de análisis de audio generada al comparar datos de audio con una biblioteca de firmas de audio; una puntuación de intensidad de audio generada al evaluar una potencia de al menos una porción de un espectro de los datos de audio; y un puntaje de análisis de video generado mediante el uso de un algoritmo de procesamiento de imágenes para analizar los datos de video. El sistema se dispone para indicar que se detecta un UAV en una o más celdas espaciales si el puntaje de probabilidad asociado excede un umbral de detección predeterminado.
