| Research Abstract |
The biosonar system employed by bats was examined based on acoustical, physiological and dynamic measurements for understanding their effective bio-navigation algorism. As a result, (1) collaboration control in flight and acoustical sensing behaviors by bats, (2) look-ahead control of pulse direction during flight, and time-sharing processing for multiple target, (3) avoidance for self-jamming (pulse-echo ambiguity) by shifting frequency range, (4) consistence of electrophysiological measures of best frequency and latency distributions in inferior colliculus of Pipistrellus abramus with behavioral measures during foraging in this species.
