Abstract :
Consider that each of a fixed number of receiving hydrophones can be placed at one of two locations to estimate the bearing to an acoustic source. For high-output signal-to-noise ratio (SNR) the hydrophones should be divided to balance the output voltage SNR. However, for low-output SNR the hydrophones should be equally divided.
