摘要

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 transducer generated in response to the insonification of a finite planar specular target, as a function of incident angle. The transducer is assumed to be operating in pulse-echo mode. The development is made via scalar diffraction theory, in terms of the angular spectrum decomposition of the acoustic source field. Numerical simulations of the FT-SD are presented for several reflector sizes and orientations, insonified by a planar circular piston transducer. Experimental verification of results for a finite square planar reflector is given for a range of reflector orientations.
