摘要

Theoretical and experimental methodology are presented fornaccurately determining the effective radii of unfocused, circular planenpiston transducers as well as using tone burst hydrophone measurementsnto verify steady-state theoretical calculations. Experiments using twonspecially fabricated unfocused, composite piezoelectric transducersndemonstrate the validity of the methodology. For spherically focusedncircular transducers, a simple model is used to estimate the transientndiffraction encountered in co-axial flat hydrophone measurements
