Abstract :
Localisation of underwater vehicles is usually accomplished by doing analog goniometry. If the number of microphones is high enough precision the process can be sufficient for an adequate signal to noise ratio. In underwater environments the signal to noise ratio decreases rapidly with distance. Furthermore measuring the SNR introduces noise. This limits the use of this technique.
