自然界提供了许多例子，其中声学回声定位是主要的感知方式，其中最知名的是蝙蝠，鲸鱼和海豚。它们都表现出“用声音看东西”的非凡能力。利用回声定位，它们可以导航、定位并捕获猎物。作为一个物种，它们不仅生存下来，而且在各自的环境中茁壮成长，通常完全依赖回声定位。所有这些生物都具有内在的认知能力。它们都通过神经系统保持对环境的感知，从而采取行动。在本文中，我们专注于蝙蝠作为认知系统的一个例子，利用记忆驱动的感知-动作循环，使其能够导航和与环境互动。认知的关键概念组成部分，以及如何将其应用于人造回声传感器。其次是如何回声流场，蝙蝠已被证明使用，适合指导和控制问题的生物启发技术的描述。然后，我们继续解释蝙蝠如何能够可靠地区分不同的目标。结合的理论和实例来展示巨大的潜力，通过采用自然回声定位认知动态系统的方面，在人造系统的能力。
Nature provides a number of examples where acoustic echolocation is the primary sensing modality, the most well known of these being the bat, whale, and dolphin. All demonstrate a remarkable ability to "see with sound.'' Using echolocation, they navigate, locate, and capture prey. As species, they have not only survived but have thrived in all their individual environments, often solely reliant on echolocation. All of these creatures are inherently cognitive. They all maintain a perception of their environment through the nervous system that allows them to take actions. In this paper, we focus on the bat as an example of a cognitive system exploiting a memory-driven perception-action cycle, enabling it to navigate and interact with its environment. The key conceptual components of cognition and how it could be applied to man-made echoic sensors is introduced. This is followed by a description of how echoic flow fields, a bio-inspired technique that bats have been shown to use, fit guidance, and control problems. We then go on to explain how bats are able to reliably distinguish between different targets. A combination of the theory and examples is used to demonstrate the vast potential for advancing the capability of made in man-made systems by adopting aspects of natural echolocating cognitive dynamic systems.
