Phase Distortion Estimation by DIRECT and Spline Interpolation Algorithms

摘要: An important cause of performance loss in source localization underwater acoustics is that towed flexible antennas deviate from the assumed rectilinear shape. In this work, sources presence phase errors studied. Cancellation necessary to solve source-localization problem. A previous work led interesting results for composed a few sensors. We propose here novel algorithm which adapted large number sensors, keeping small computational load. Our method based on an orthogonality property between signal and noise subspaces optimization method: robust dividing rectangles accelerated by spline interpolation. The performances proposed are illustrated applying it characterization three sources.
