ABSTRACT:
A zero velocity towed array system for use in an ocean environment includes towed array subsystem and a deployment vessel. The towed array subsystem comprises a rear drogue, an elongated communication cable having mounted thereon at least one. acoustic sensor. The deployment vessel deploys the towed array subsystem. While the deployment vessel moves in a forward direction through the ocean environment at a selected forward motion rate, it deploys the acoustic sensor and communication cable rearwardly at a deployment rate corresponding to the forward motion rate, thereby to maintain the acoustic sensor and communication cable in a stable position in the ocean environment.
