Abstract

A new spatial-vector smoothing algorithm for multiple coherent sources is proposed based on the measurement model of 3-D cylindrical array with multi vector-hydrophones, which is located on or near a reflecting boundary. And the performance of the proposed algorithm is examined in two practical applications: hull-mounted and seabed array. The advantages of the spatial-vector smoothing scheme are: (1) less reduction in the overall array´s spatial aperture, (2) no limit to the maximum number of coherent sources
