Variability in the Pinna Motions of Hipposiderid Bats, Hipposideros Pratti
… and hipposiderid families, have complicated pinna motion patterns. It has been shown that these pinna motion patterns fall into two distinct categories: rigid motions and non-rigid motions. In the current work, the pinna of Pratt's leaf-nosed bat (Hipposideros pratti) was used as a biological …

Machine Learning Approaches for Biosonar Systems: Investigating Dynamic Sensing in Complex Natural Environments
… of this research established that static pinna shape variations create consistent, discriminable effects on clutter echoes despite their stochastic nature. Using a biomimetic robotic pinna capable of producing ten distinct conformations, we recorded over 50,000 clutter echoes from …

The Role of Actively Created Doppler shifts in Bats Behavioral Experiments and Biomimetic Reproductions
… remain often unclear. Through fast ear motions, bats can encode information on target direction into time-frequency Doppler signatures. These species were thought to be evolutionarily tuned to Doppler shifts generated by a prey's wing beat. Self-generated Doppler shifts from the bat's …
