蝙蝠、鲸鱼和海豚等回声定位哺乳动物即使在密集、杂乱且通常充满敌意的环境中也能够探测、选择和攻击猎物。它们发展回声定位技术已有超过 5000 万年的历史，并依靠卓越的表现来生存。尽管雷达传感器和回声定位哺乳动物使用的频率和波形参数并不相同，但仍然存在密切的相似之处，这表明可以从自然界中吸取教训。在本章中，我们研究回声定位蝙蝠在检测、定位、跟踪和捕获猎物方面的行为和表现。我们展示了回声定位呼叫如何根据执行的任务以动态和智能的方式多样化，并将结果与典型的飞行轨迹联系起来。我们讨论如何将回波转化为对目标的有意义的感知，最后我们探讨如何使用这些信息来开发雷达自动目标识别（ATR）的新架构。
Echolocating mammals such as bats, whales and dolphins are able to detect, select and attack prey even in dense cluttered and often hostile environments. They have developed echolocation for over 50 million years and rely on exceptional performance for their survival. Although the frequencies and waveform parameters used by radar sensors and by echolocating mammals are not the same, there remain close parallels that suggest lessons can be learnt from nature. In this chapter, we investigate the behaviour and performance of echolocating bats in terms of detecting, locating, tracking and capturing prey. We show how echolocation calls are diversified in a dynamic and intelligent manner according to the task performed and relate the results to typical flight trajectories. We discuss how echoes may be transformed into a meaningful perception of the target and finally we explore how this information can be used to develop a new architecture for radar automatic target recognition (ATR).
