Pc. Pedersen et Dp. Orofino, MODELING OF RECEIVED ULTRASOUND SIGNALS FROM FINITE PLANAR TARGETS, IEEE transactions on ultrasonics, ferroelectrics, and frequency control, 43(2), 1996, pp. 303-311
This paper presents a computational solution to the ultrasonic target-
dependent spectral distortion for a finite planar target (FT-SD), The
FT-SD predicts the spectrum of the output signal from the receiving tr
ansducer generated in response to the insonification of a finite plana
r specular target, as a function of incident angle, The transducer is
assumed to be operating in pulse-echo mode, The development is made vi
a scalar diffraction theory, in terms of the angular spectrum decompos
ition of the acoustic source field, Numerical simulations of the FT-SD
are presented for several reflector sizes and orientations, insonifie
d by a planar circular piston transducer. Experimental verification of
results for a finite square planar reflector is given for a range of
reflector orientations.
