Abstract

A range estimation scheme is proposed when a moving object is located within the forward scattering coverage. It is based on acoustic field aberrations of the stable arrival caused by forward scattering of the moving object. The durations of acoustic field aberration are measured by transmitting a signal continuously, and then the range of the moving object is estimated if a priori knowledge of the moving speed is supposed to be known. The acoustic field aberrations of the experimental data are clearly observed after matched filtering, and the estimated ranges of the object agree well with the true values.
