Dolphins use some sort of temporal beamforming to steer their sonar
Dolphis can steer their sonar using some kind of beamforming technology.
Dolphins can steer their sonar +- 20 degrees left and right by emitting multiple clicks. This seems somewhat similar to beamforming, or perhaps more akin to a directional microphone. I don’t understand the physics of it, but perhaps I can get hold of the actual paper and figure out more. Sounds pretty nifty.
