Designing Critical Experiments on Detection and Estimation in Echolocating Bats

  • Dieter Menne
Part of the NATO ASI Science book series (NSSA, volume 156)


The similarity between sophisticated echolocation signals of bats and those of man-made sonar and radar has been a challenge to biologists and engineers since many years. The similarity in the structure of these signals suggested that their function might be analogous, and that signal processing in radar receivers and the brain of bats might be based on the same principles. The aim of many experimental studies has been not primarily to discover the limits of echolocation, but to find how these limits are imposed by characteristics of the signal and their processing in the nervous system. The most far-reaching goal of this approach has been to use behavioral data to predict possible receiver models that can be tested with electrophysiological methods.
