Abstract
For a class of scattering objects the mean separation between the scatterers is determined. Over a range of frequencies, ultrasonic back-scattered pressure signals are recorded. It is suggested to derive the mean spacing of an unknown scattering object by employing Fourier analysis and comparing the signal with signals from known regular arrays of scatterers. In a computer simulation it is shown that this approach determines the mean spacing very well for random arrays consisting of three-dimensional spherical scatterers.Keywords
