Abstract
The Born inversion of time records of acoustic pulses reflected from a laye r object gives rise to the images with ghost-like artifacts that make it di fficult 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 thei r suppression. (C) 2000 Elsevier Science B.V. All rights reserved.
