A solution to the problem of bearing estimation of multiple sound sources in a shallow ocean waveguide is developed. A planar array of N vertical columns of Q hydrophones each is used. Each vertical column is used as a mode-filter to extract the same normal mode from among the many propagating in the waveguide. It is shown that a two-column planar array used in conjunction with a delay-and-sum array processor would suffice to estimate the source bearing. When multiple sources are present, thedoi:10.1109/tencon.1989.176936 fatcat:ualn7qbfhbfnpm2rigag5zgqey
