Impacts of Mesoscale Eddy Structural Characteristics on Matched-Field Localization Uncertainty Open
Matched-field processing localizes underwater acoustic targets by measuring the degree of correlation between the acoustic field and replica fields. The intrusion of mesoscale eddies can induce sound speed mismatch in the matched-field pro…

Striation-Based Beamforming with Two-Dimensional Filtering for Suppressing Tonal Interference Open
Based on the interference spectrogram in the element–frequency domain using the data measured by the horizontal linear array, the source range can be estimated through the striation-based beamforming (SBF) method and its variants. Estimati…

Prefiltered Striation-Based Beamforming for Range Estimation of Multiple Sources Open
The element–frequency acoustic intensity of a horizontal line array with a sufficient aperture exhibits interference striation patterns, which can be used for source range estimation without prior environmental information. Under multisour…
