Chapter 30 — Sonar Sensing

Antwerp biomimetic sonar tracking of a single ball

The Antwerp biomimetic bat-head sonar system consists of a single emitter and two receivers. The receivers are constructed by inserting a small omnidirectional microphone in the ear canal of a plastic replica of the outer ear of the bat Phyllostomus discolor. Using the head-related transfer (HRTF) cues, the system is able to localize multiple reflectors in three dimensions based on a single emission. This movie demonstrates the tracking of a single ball target.
