Abstract : This report presents Space and Naval Warfare Systems Center Pacific's (SSC Pacific) preliminary efforts to implement and test the JANUS acoustic communication protocol onto a software-defined acoustic modem previously developed by engineers working at the Center. The SSC Pacific developed acoustic modem serves as an ideal open platform suitable for testing and evaluating physical layer protocols such as JANUS, which has recently become a North Atlantic Treaty Organization (NATO) adopted standard. The system configuration, implementation approach, laboratory, tank, and field tests at SSC Pacific's Transducer Evaluation Center (TRANSDEC) facility are discussed. The outcome of the preliminary testing and several lessons learned have paved the path for a promising future effort to create an integrated software-defined interoperable solution for the U.S. Navy's underwater acoustic communication operations with NATO and non-NATO military and civilian maritime assets.
