摘要

摘要通过实验研究了海豚对海洋沉积物遮挡物定位的声纳适应能力。研究表明，海豚能够改变其定位信号的光谱和时间特征。信号长度、谱宽和幅度的自适应变化提供了对抗干扰的最佳工具，使海豚能够有效地识别物体。

Adaptation of dolphins’ (Tursiops truncatus) location signals when searching for and identifying objects hidden by sea sediments

ABSTRACT An experimental study was conducted to research dolphins’ sonar adaptation capabilities for location of objects obscured by marine sediments. It was shown that dolphins are able to alter spectral and temporal characteristics of their location signals. Adaptive change in length, spectral width and amplitude of signals provides optimal tools to fight interference and allows dolphins to effectively identify objects.
