Abstract
An investigation is presented into the presence of spatial aliasing due to the operation of a linear array in the near-field. It shows that the standard half wavelength sensor spacings rule, which guarantees that no aliasing will occur in the operation of far-field arrays, is not sufficient to prevent aliasing in the near-field. This claim is justified by theoretical considerations and corroborated by simulation results.
