Short Pulse Propagation Between Thick Transducers in a Water Medium

Kozina and Hakarov (1] showed that a transient disturbance in the field of a baffled plane piston radiator consisted of a direct wave which was geometri' cally bounded by a right prism with the piston surface as base and an edge wave which was radiated from a line source around the periphery of the piston.Both components radiated into the half space in front of the piston and combined in opposite phase in the acoustic field.This combination can be described by an equivalent impulse response L2].The field response to any real source velocity function is derived in the time domain by convolution.For short
