This paper proposes to explore the potential of Blind Source Separation (BSS) techniques for the estimation of modal parameters, namely the resonant frequencies, vibration modes and damping ratios. The concept of virtual sources, which was introduced in recent publications, allows to consider BSS as a simple way of doing output-only modal analysis. This work illustrates the proposed methodology using free and random responses of an experimental truss structure. © Springer-Verlag Berlin Heidelberg 2007.
