A Conceptual Navigation Sonar System (CNSS) is proprosed for demonstration. This CNSS has the potential to remove or alleviate many of the short comings of the the current AN/BQN-25, including being able to operate nearly continuously. This is achieved by using a phased array to generate steerable beams and modern transducer technology which has a very low Q.
