The distance to such objects can be estimated by the time difference between the sent signal and received echo times half of the speed of sound. This approach is an example of active sensing, since bats actively echolocate to localize objects, rather than passively receiving an existing environmental signal. Studies on pairs of bats show that one of them may cease echolocation to prevent signal jamming. This behavior suggests that only passively listening to the echo from another bat is enough for garnering sufficient information about the location of obstacles in the environment. This paper studies the possibility of passive localization through numerical simulation and demonstrates a strategy to passively use echolocation signals for localization. This work paves the way for energy optimization in a robot swarm.
