Abstract
The determination of local reflectivity characterizing the interior of a unknown object from acoustic impulse echo data might be considered as a standard problem of acoustical imaging. In many cases this inverse problem can be formulated as a deconvolution problem. By one-dimensional axial deconvolution of a single time trace, assuming plane wave propagation, an estimate of the acoustic impulse response of the scatterer is obtained within the usable band-width of the transducer. This one dimensional scattering function enables an improved discrimination of echoes of one or more reflectors [1], For special cases like the analysis of a discrete layered medium, a priori information can be used in order to extend the usable frequency range [2], In [3] the lateral resolution is increased by deconvolution with the spatial characteristics of the transducer. In these cases only one part of the complex transducer characteristics is considered.
