Abstract
In order to develop the ability of localization of the underwater target in shallow sea, a method of localization with multi-array is proposed in this paper. This method employ matched field processing (MFP) combined with vertical line arrays (VLA) and horizontal line array (HLA) to sample the sound field in large scale to get the 3-D information of the target. The multi-array is built by take a full account the affect of waveguide in shallow sea comparing with single array, which can overcome the twin-line arrays port/starbord blur problem and achieve the estimation of range and azimuth effectively. The localization is realized by a MFP and the results from simulations and data processing is more reliable in complex shallow sea environment than with single array MFP.
