| Outline of Final Research Achievements |
This study aims to elucidate the mechanism of jamming avoidance behavior in acoustic sensing by bats during group flight, and to direct toward knowlegds for engineering applications. Echolocating bats are classified into two types, FM bats and CF-FM bats, based on the difference of ultrasounds. We found that FM bats avoid acoustic interference by changing frequencies, and then also implemented this behavior mechanism in autonomous vehicles and evaluated it through obstacle avoidance driving under interference. As a result, we could confirm that the bat tactic is useful from an engineering standpoint. On the other hand, we also found that the Doppler shift compensation behavior of CF-FM bats reduces the interference of signals from other individuals.
