Fourier–Bessel theory is used to derive a closed-form solution for the spatially averaged velocity-potential impulse response associated with one-way diffraction from an unfocused piston transducer of radius a. The derivation provides additional insight into the problem of diffraction from an unfocused piston transducer.
