The large differences in the wavelength of visible light and the ultrasonic pulses of bat biosonar raise the question whether the sensory world of bats is the same as that of humans and other visual animals, completely different, or something in-between. Pioneering research on this question has focused on the range dimension of biosonar perception exploiting the straightforward relationship between echo delay and target range. Furthermore, since bat ears are typically no more than a single order of magnitude longer than the respective ultrasonic wavelengths, the beam patterns of the animals are fairly wide, which can be expected to result in a much better resolution for range than along the cross-range dimension. Bats that use their biosonar to navigate in densely vegetated environments receive echoes containing contributions from many unresolved scatterers, i.e., “clutter echoes.” Extracting useful information from clutter has been studied using real-world data collected with biomimetic sonar systems and analyzed with deep-learning methods. The results demonstrate that useful information can be extracted from clutter echoes without the formation of an image, i.e., without a systematic spatial representation of resolved objects. Hence, many interesting aspects of how bats experience their sensory worlds may still be left to be discovered.
