回声定位哺乳动物，如蝙蝠，鲸鱼和海豚已经使用波形多样性超过5000万年。它们改变所发射波形的PRF、功率和频率内容。这使它们能够进化出高度复杂的导航技术和觅食能力。此外，最近的技术发展意味着，现在有可能在雷达和声纳等合成系统中复制哺乳动物使用的许多方法。因此，回声定位哺乳动物可能提供有价值的见解，可能会允许这些合成传感器同行的改进，使自主导航的平台和自动目标分类。在本文中，作者研究了蝙蝠使用的波形作为方向和意图的函数。这些信息以雷达界熟知的形式提供，包括功率谱、模糊函数。从这个分析中，作者能够理解蝙蝠如何利用波形多样性，以及如何在雷达和声纳系统中复制。
Echo locating mammals such as bats, whales and dolphins have been using waveform diversity for over 50 million years. They vary the PRF, the power and the frequency content of the transmitted waveforms. This has enabled them to evolve highly sophisticated navigation techniques and the ability to forage for food. Moreover, recent developments in technology means that it is now possible to replicate many of the methods employed by mammals in synthetic systems such as radar and sonar. Thus echo locating mammals potentially offer valuable insights that might allow improvements in these synthetic sensor counterparts enabling autonomous navigation of platforms and automatic target classification. In this paper the authors examine the waveforms used by bats as a function of orientation and intent. The information is presented in terms forms well known to the radar community and includes, power spectra, ambiguity functions. From this analysis the authors are able to derive understanding as to how bats are exploiting waveform diversity and how this can be copied in radar and sonar systems.
