Abstract

La invención es concerniente con una sonda que incluye NE transmisores de ultrasonido (11) y NR receptores de ultrasonido (12) que es aplicada al medio ambiente a ser caracterizado. El método comprende activar consecutivamente cada transmisor (11) y cada vez recolectar las señales en todos los receptores (12) durante una ventana de tiempo. Cada una de las NE y NR señales es convertida por una transformada de tiempo de Fourier en una suma de componentes vibratorios, cada uno tiene su propia frecuencia de tiempo. El método comprende derivar, para cada frecuencia, una matriz de NE x NR de las amplitudes complejas de los componentes vibratorios que tienen dicha frecuencia. Las matrices (una por frecuencia) son descompuestas en valores singulares, los más pequeños son removidos y el método comprende además formar con los vectores singulares asociados con los valores singulares restantes, una base del espacio de las señales de recepción para cada frecuencia. El método también comprende calcular la distribución de cada onda plana caracterizada por la velocidad de la misma (frecuencia de espacio) en dicha base. Dicha contribución es representada en forma de un nivel de grises en un sistema de frecuencia - velocidad de propagación. La invención puede ser usada para una mejor caracterización de medios ambientes, en particular los ruidosos.
