Study on biosonar in bats for engineering application

为了了解蝙蝠有效的生物导航算法，对蝙蝠使用的生物声纳系统进行了声学、生理和动态测量。其结果是：(1)蝙蝠在飞行中的协同控制和听觉感知行为；(2)飞行中脉冲方向的前瞻控制和多目标的分时处理；(3)通过改变频率范围来避免自我干扰(脉冲-回声模糊)；(4)最佳频率和潜伏期分布的电生理测量与该物种觅食过程中行为测量的一致性。

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.
