Mathematical and software-hardware tools for modern hydroacoustic monitoring systems

Abstract

The paper discusses filter bank implementations in hydroacoustic monitoring tasks and a new modification of the weighted overlap-add algorithm for vector (multichannel) signal processing. We provide the results of filter bank implementation using the central processing unit and the CUDA technology and show that CUDA is more efficient for long signal sets. Finally, we cover some aspects of data visualization in hydroacoustic monitoring tasks.
