Abstract

Centralized sampling acquisition systems are commonly used to acquire and digitize data from arrays of acoustic sensors. These systems have centralized/co-located connection points for multiple sensor channels and contain digitization and processing electronics that can be shared across these inputs. While this system architecture can simplify the electronics design, it has several intrinsic properties that degrade the data quality and increase system complexity for certain application parameters. Advancements in high speed, low power electronics have made distributed sensor digitization feasible for applications with limited available power such as remote underwater surveillance and autonomous underwater vehicle systems. This paper explores some limitations of centralized systems in underwater acoustic applications and presents some examples of where the benefits of distributed digital sensors were realized.
