Harbour Porpoise Localization System Using Compact Acoustic Sensor Arrays

The objective of this work is to develop a localization system using a compact array capable of obtaining a coarse estimate of the location of high frequency echolocation pulses emitted by harbour porpoises. This work improves upon a traditional grid search by using a lookup table which is stored in a hyperoctree to reduce the computation time required to perform the localization. Additionally, the impact of the sensor geometry is analysed to improve the accuracy of an existing sensor configuration. Finally, the impact of the noise on the measured signal is analysed and mitigated by using various preprocessing techniques.
