Bats´ acoustic detection system and echolocation bionics

Bats´ acoustic detection system was introduced, including the nose-leaf for emission, two ears as receive antennas and the stimulus data flow in the auditory system. The waveform design and signal processing method in the echolocation system was analyzed in details. Further more, a bionic model was established based on the main function of bat´s ear. The model was simulated for bat´s echolocation stimulus. Simulation results imply that the bionic signal processing method is high accuracy, sharp resolution and robustness in localization. Echolocation bionic design can be a new way to promote the capability of artificial sonar and radar system.
