Theoretical investigation of active listening behavior based on the echolocation of CF-FM bats
Bats perceive the three-dimensional environment by emitting ultrasound pulses from their nose or mouth and receiving echoes through both ears. To determine the position of a target object, it is necessary to know the distance and direction of the target. Certain bat species that use a combined signal of long constant frequency and short frequency modulated ultrasounds synchronize their pinnae movement with pulse emission, and this behavior has been regarded as helpful for localizing the elevation angle of a reflective sound source. This paper describes a simple mathematical model for investigating the active listening strategy employed by bats. Hiraga et al 2022
