Typical power spectral density plots of the acoustic signals (averaged across all pings) collected with the solid sphere targets show that acoustic signals are primarily in the 10-30 kHz band of the transmitted waveform. This power is substantially higher than the background noise, and is consistent across all four channels. This demonstrates that the acoustic signals scattered from the background and targets have a high SNR.
