Using a point source superposition method, the signals from spherical, cylindrical and crack‐like reflectors observed in a pulse‐echo measurement are predicted. Normally incident longitudinal waves as well as obliquely incident transverse and longitudinal waves, generated by circular focused and unfocused transducers, respectively, of 5 MHz center frequency are assumed in an immersion geometry. Three sets of scattering objects are considered: spherical pores, cylindrical scatterers and circular cracks of various diameters. The problem addressed in this contribution is an extension of the 2001 UT Benchmark Problem [1]. © 2003 American Institute of Physics
