Abstract
An echograph includes a transmission stage (20), a circuit (31) for suppressing fixed echos, and a correlation-interpolation circuit (33). The the transmission stage (20) transmits a pulsed signal having two neighboring, alternating recurrent periods T.sub.1 and T.sub.2, the fixed echo suppression circuit (31) being adapted to double the recurrent period and comprises two outputs having the index even and odd, the correlation-interpolation circuit (33) performing, for each velocity, two distinct correlations, one of which is associated with the period T.sub.1 whereas the other is associated with the period T.sub.2, after which these two correlations are compared so as to derive a non-ambiguous velocity value therefrom.
