Sonar signals are conventionally divided into two categories: (1) shaped, broadband components, such as ambient, ship flow and propeller cavitation noises, and (2) narrowband components, including machinery noise, echoes, and reverberations. This paper will explain how Honeywell uses digital data processing to generate these signals for use in sonar trainers.
