A Study to improve a Target Localization Performance using Passive Line Arrays buried in the Seabed
매설된 선배열 음향센서를 이용한 표적 위치추정 성능향상 기법 연구
Abstract
The target localization using the line arrays buried in the seabed is a difficult problem due to the complex sea bottom characteristics and need to compensate the wave propagation effect to localize the target accurately Sound speed mismatch in the seabed causes a bias in the target bearing estimation and induces the localization error. In this paper we describe a target localization method with improved accuracy of target bearing and localization by calibration the sound speed in the seabed. The proposed algorithm is verified through the ocean data.
