Acoustic Processing
Introduction
One of the major tasks for unmanned underwater vehicles is to find the location of an underwater acoustic signal's source. Using MathWorks tools, users can import data into a desktop computer from data acquisition devices, design and implement acoustic processing algorithms on the desktop computer, and generate HDL code for FPGAs to perform real-time acoustic processing. There are a wide variety of signal processing tools that can be used to design and visualize acoustic processing algorithms. As an example, there are tools available to design filters, simulate the propagation of acoustic signals in fluids, and design cross correlation algorithms.
