Noise source coordinate estimation in shallow water with a vector-scalar horizontal linear array

The simulation of the algorithm for the wideband noise source detection and depth and range estimation in passive mode with the Bartlett matched field processor is performed. Response characteristics of vector-scalar and scalar long-aperture linear arrays are compared. It is shown that robust coordinate estimates are obtained even when accurate waveguide parameters are not known and when there are moderate dynamic perturbations in a water column. It is found that the vector-scalar array has 5 to 10 dB higher signal-to-noise ratio than the scalar one with the same aperture.
