Enhanced Underwater Acoustic Communication via Active Field Control

ABSTRACT In this paper, an active source control scheme for manipulation of the acoustic field in ocean environment is presented. This active field control is formulated as an inverse source problem, where the target is to maximize the radiated power in several far directions while keeping a low radiated power in one or more other far field regions. Hence, the controlled source enables acoustic beamforming, i.e., enhancing the acoustic wave-based underwater wireless communication. Numerical simulations are performed to demonstrate the good performance of the proposed method.
