Principles of Perception in Bat Sonar

Abstract

This report describes the scientific findings of a program of research supported by the Office of Naval Research on echo processing and acoustic imaging by the biological sonar of bats. Results and conclusions cover the performance of bat sonar in critical benchmark tasks, the auditory neurophysiological mechanisms for echo reception and signal processing, and the computational basis for transforming waveforms of sonar broadcasts and echoes into acoustic images. The research identifies the nature of the algorithms bats use to process echoes and suggests methods for emulating critical aspects of performance in man-made systems.
