Current sonar domes do not provide best performance acoustically such as the insertion loss is high at high frequencies. Also, they do not cover wide band of frequencies of interest. Sonar domes materials have changed very little for over 20 years. There are new materials in the market which should be evaluated for the Navy applications.
Benefits: Development of the new material can be used for fishing boats, and radar domes for the aircraft industries.
