A New Concept of Echo Evaluation in the Auditory System of Bats

  • Karl J. Beuter
Part of the NATO Advanced Study Institutes Series book series (volume 28)


Bats use their echolocation system very effectively for spatial orientation and prey hunting. Important tasks bats are able to perform are the detection of weak target echoes or echoes superimposed by clutter-interference, the precise localization of targets, and the identification of target structure.
