Introduction

The core goal of this project is to design and implement a distributed algorithm for use in ranging of acoustic sources.

Problem Setup

Deliverables

Forrest will be in charge of hardware implementation and simulation while Scott will be in charge of algorithms and software implementation.

  • Global Algorithm for estimating source positions
  • Distributed/Systolic Implementation for RALA-like array/ring/surface
  • Simulator of environment, detection, filtering to test algorithm performance
  • Hardware implementation

    Simulation Progress

    The following are some simulations that model coherent addition of sound sources by introducing a time lag at each node. Attenuation with distance is not included.

  • Target Audio Source
  • Unwanted Audio Source
  • 20 nodes in a 1.2m diameter circle seperating two audio sources that are 20cm apart at 0.7m to the closest node
