The purpose of this paper is to provide a complete, rigorous and detailed analysis of the scattering far-field of a nondiffracting parabolic beam by a rigid sphere centered along the propagation axis of this beam. By use of a partial wave series involving the scattering polar angle relative to the beam axis, the half-cone angle of the wave vector components of the parabolic beam, and the azimuthal angle, we evaluate the far-field scattering distribution. We also illustrate the obtained results with some numerical calculations.
