Abstract
A system including a mechanism emitting successive acoustic waves in a medium, a mechanism receiving the successive acoustic waves after propagation thereof in the medium, configured to supply a reception signal based on the successive acoustic waves received, and a mechanism detecting and locating disturbance in the medium on the basis of the reception signal. The emitting mechanism is configured such that, amplitude and/or phase spectrum of each acoustic wave having, at a specific frequency at least, an amplitude, or phase, varying in the medium according to a specific spatial distribution of the amplitude, or phase, and the spatial distributions of the amplitude, or phase, of the successive acoustic waves are mutually different.
