The broadband FM signals and the narrowband CF signals travel out to a target, reflect from it, and return to the hunting bat.

Responding to changes in the CF echo's frequency, bats of some species correct in flight for the direction and velocity of their moving prey.
有些种类的蝙蝠会根据回声频率的变化来调整向猎物移动的方向和速度。

Because of their narrow bandwidth, CF signals portray only the target's presence and, in the case of some bat species, its motion relative to the bat's.
