Estimate of Direction-of-Arrival Using a Horizontal Line Array

Abstract

Source localization in underwater sound field is one of the hot research topics in underwater acoustics [1-2].Since the estimate of direction-of-arrival (DOA) using horizontal line array (HLA) provides the azimuthal angle of the sound transmitted from the target. The HLA has been used in a variety of applications, such as naval sonar system for detecting and tracking underwater targets and acoustic remote sensing of marine life.nsmitted from the target. The HLA has been used in a variety of applications, such as naval sonar system for detecting and tracking underwater targets and acoustic remote sensing of marine life.
