Not neccessarilty. The signal will be continously time shifted with or without a transient. As the sound is continuously intercepted, the signal/sound waves should have a predictable latency real-time, imho. Though how accurately it could be determined I don't know.

The SURTASS TL-29A twin-line system is an underwater passive acoustic sensor with a pair of arrays towed side-by-side from a ship. The TL-29A delivers unsurpassed capabilities, such as its ability to be towed in very shallow water environments in the littoral zones, to provide significant directional noise rejection, to resolve bearing ambiguities without turning, and to allow the ship to tow at higher speeds

The twin-line array, which was developed by a joint government-industry team comprised of the John Hopkins University Applied Physics Laboratory, Chesapeake Sciences, and the Navy’s Array Technical Support Center, Little Creek, Va. employs COTS telemetry architecture and consists of two short parallel acoustic arrays separated by several meters. The array provides for left-right ambiguity resolution, back lobe rejection, and the flexibility to tow in shallow water

So this capability already exist and is probably already deployed in some regards... only question is whether the distance seperating two TA on a submarine is sufficient enought to do the job... :hmm:

Down with bearing ambiguity!! .... at least for US subs
