ABSTRACT : Apparatus for the scanning of objects by means of ultrasound echography. An apparatus for the scanning of objects by means of ultrasound echography, comprising a mosaic (10) of ultrasound transducers which is connected to a transmitter stage (20) and a receiver stage (30) for the reception and processing of the ultrasound echo corresponding to the ob- stacles encountered by the transmitted signals in their direction of propagation, and also comprising a display stage 40. The transducers of the mosaic (10) are grouped in 2n subwindows in which a non-corrected echogram of an area of the objects scanned is formed. The receiver stage (30) comprises a device for determining correction delays to be applied to delay devices (61 ... 68), said device comprising 2n-1 intercorrela- tion circuits (101,102, ect.) which operate on the basis of n successive divide-by-two operations of the aperture of the mosaic (10).
