Sonar for naval applications was originally developed to detect and locate large underwater threats such as submarines, in deep water. This deep water sonar is not very effective at locating smaller objects such as mines, especially in shallower water. It became well known that in order to detect and localize small objects in the water, higher sonar frequencies were required. The use of these higher frequencies added significant complexity to the systems required to acquire and analyze the sonar data. This paper will look at traditional solutions to the implementation of a high frequency sonar system and compare them to one of the simpler solutions available with modern FPGA enabled hardware offerings.
