title: Ghosts in the Born images of a layer probed by acoustic waves.
abstract: The Born inversion of time records of acoustic pulses reflected from a layer object gives rise to the images with ghost-like artifacts that make it difficult to pick out the exact thickness and composition of the object. The origin of these ghosts is explained herein and a means is proposed for their suppression.
