ABSTRACT:
A baffle structure for use with an electroacoustic transducer in a sound ranging system eliminates secondary reflections between the transducer and target, thus eliminating false target errors that occur in conventional sound ranging systems due to phantom target indications caused by multiple reflections between the transducer and target.
