Pulse Duration in the Echolocation of Insects by the Bat, Pteronotus

  • Alvin Novick
Part of the Ergebnisse der Biologie / Advances in Biology book series (ERGBIOL, volume 26)


The pulse durations of the orientation sounds of the bat, Pteronotus, are progressively shortened during the pursuit of a fruit-fly. If the position of the bat is calculated for each pulse, the echo from the fly is found to overlap the pulse by about 1.5 msec, in the approach phase, and by about 1.0 msec, in the terminal phase of each pursuit. Such pulse-echo overlaps has not previously been demonstrated in bats.
