PhD Presentation: Low-power detection of underwater acoustic signals
Detection of underwater acoustic signals is an area of interest in many different fields, such as environmental science, marine biology, maritime archaeology and security.
The acquisition and analysis of those signals is energy-intensive due to their high-bandwidth nature. Using novel hardware and software solutions that minimize the power required for performing those tasks can greatly improve the battery life of underwater acoustic surveillance systems. This presentation will introduce the low-power time-frequency pattern wake-up detector developed as part of the AWAKE project and the framework of a doctoral research project, the aim of which is the development of an ultra low power embedded sensor system for the detection of acoustic signals produced by divers.
