Abstract:
In a recent paper, we have shown experimental results of ultrasound wave velocity and attenuation coefficient measurement in macroscopic suspensions. The experimental method was shortly described. This spectroscopy method allows measurement over a broadband frequency spectrum in a strong absorbing and high dispersive medium. The originality of the method lies in the automatic signal processing that suppress the ambiguity in the determination of the signal phase. The present paper deals with the detailed description of the signal processing that we use.
