Data from sonar beam pattern measurements and modeling of free-flying Rousettus aegyptiacus

Concurrent broadband microphone and high-speed video camera recordings of free-flying Egyptian fruit bat (Rousettus aegyptiacus). The experiment was designed to record and reconstruct broadband, two-dimensional (azimuth and elevation in a bat-centered coordinate system) beam pattern from this interesting lingual-echolocating bat species. These bats produce alternating left- and right-pointing clicks as pairs during navigation and target localization, with very short inter-click intervals (~20 msec) within each pair.
