title = "Effects of eddy on close range DOA estimation",
abstract = "In this paper, Argo data combined with altimetry data were used to investigate the effect of eddy on Sound Speed Profile (SSP) in Northwestern Pacific Ocean. A combination of the closed contours method and the Okubo-Weiss method is used to detect the eddy. Statistics of SSP anomalies induced by eddy have been calculated by removing the climatology from Argo profiles in eddy. Then effects of eddy on close range Direction of Arrival (DOA) estimation have been studied with a conventional beamforming method. Results suggest that the DOA estimation performance may deteriorate due to presence of the eddy. The deterioration occurs when the receiver is placed near the direct path range. This is because the direct path range is sensitive to the SSP anomalies and the presence of the eddy may lead to the receiver falling in/out of the direct path range.",
