Animal echolocation

（重定向自Biosonar）

A depiction of the ultrasound signals emitted by a bat, and the echo from a nearby object.

Spectrogram of Pipistrellus Bat vocalizations. Detail is shown as the pulses transition to a faster repetition rate. The bat appears to use a hybrid pulse which combines a sharp falling frequency chirp with an extended constant frequency tail. Such a waveform may offer combined benefits of range estimation as well as Doppler shift detection.

Echolocation, also called bio sonar, is the biological sonar used by several kinds of animals Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation and for foraging (or hunting) in various environments. Some blind humans have learned to find their way using clicks produced by a device or by mouth.
