Abstract
A system and method thereof identifies and locates a submarine or other similar object located in the ocean. The thermocline in the water column is utilized to identify objects based on signals carried by the internal wave (IW) in a mixed layer (ML) of water established between a less-dense and/or warmer upper layer of water and a more-dense and/or cooler lower layer of water. The system can detect objects moving in the ML. Additionally, the system detects non-moving objects in the ML based on shadowing and/or scattering effects established by naturally occurring waves contacting the object.
