A bottom-mounted horizontal array is proposed for range estimation and depth discrimination of multiple sources where the SSP information of the environment is not required. The two key elements are, first, to use the horizontal array for deriving modal wave numbers and composite modal amplitudes excited by multiple sources in multiple frequencies and, second, to utilize the frequency samples for obtaining unknown source ranges and discriminating source depths.
