Abstract

The method involves evaluating sound from the target received directly and via reflections. The hardware includes a submerged receiver with a number of electroacoustic transducers. The electrical output signals off the transducers are added directionally selectively to form group signals and transition time differences between direct and indirect paths determined and compared with modeled differences with various target position assumptions until agreement is achieved.
