We are happy to share our new open access publication "Off-axis targets maximize bearing Fisher Information in broadband active sonar" which combines mathematical predictions with empirical measurements of a bottlenose dolphin. We derived the bearing Fisher Information encoded in the frequency-dependent transmitted beam of a bottlenose dolphin and found that the optimal strategy for obtaining target information is to direct the beam slightly askew of the target. We also recorded the echolocation behavior of dolphin and found the dolphin behaved in agreement with our predictions.
