Abstract
Continuous communication is possible only when submarines deploy a receiving antenna while operating at or near the surface. This imposes a restriction upon the submarine's operating depth and its speed, as well as increasing its exposure to detection. Low Frequency Long Range Acoustic Communications has the potential to meet some of the needs in this long standing capability gap. Operating at lower frequencies offers more range at the expense of bandwidth, and has been explored to some degree, but research in the 100 to 200 Hz range has been hampered by the lack of a suitable projector. Develop a coherent acoustic projector that will provide 50-75 Hz of BW on a 300 Hz carrier at a depth of 1000 m.
