项目摘要

One of the special aim of this project is to realize the cooperative observations among the engineers and zoologists to investigate the echo location behavior perforned by bats or dolphins. Because, in general, the engineers haven't the chance to observe the natural features of these animals, on the other hand, the zoologists also haven't the tools to approach to the echo location mechanism. Project investigators are organized by engineers, zoologists and physiologists, and they are divided into two groops, one is for bats and the other is for dolphins. Usual discussions are perforned using the inter-net, so that the frequent and quick responses are realized over all investigators of this project. To discuss the obtained results of each investigators in directly, whole meeting were held five times. The creative discussion were perfornrd in the cooperative observations of echo location signals of bats and dolphins. The cooperative observations were also held two times.Obtained results show that the bio-SONAR has many advantages compare with the artificial SONAR in the features of small size in dimension, signal processing ability and flexibility. Especially, processing way of echo signal in brain gives us important suggestion, that is, in the bio-SONAR, the combination of time and frequency domain analyses just like the sonagram is skillfully used to recognize the circumstance information in their telangiectasia and brain center in instantaneously, For the engineering application, it is expected that the algorithm of signal processing in human auditory sense can applicable to study the echo location mechanism.

本项目的一个特殊目的是实现工程师和动物学家之间的合作观测，以研究蝙蝠或海豚的回声定位行为。因为，总的来说，工程师们没有机会观察这些动物的自然特征，另一方面，动物学家也没有工具来探讨回声定位机制。项目调查员由工程师、动物学家和生理学家组成，分为两组，一组是蝙蝠，一组是海豚。通常的讨论是通过互联网进行的，这样就实现了对本项目所有研究人员的频繁和快速的反应。为了直接讨论每个调查人员的调查结果，整个会议举行了五次。在蝙蝠和海豚回声定位信号的合作观测中进行了创造性的讨论。结果表明，与人工声纳相比，生物声纳在体积小、信号处理能力和灵活性等方面具有许多优势。特别是脑内回波信号的处理方法给我们提供了重要的启示，即在生物声纳中，像声图一样巧妙地利用时频域分析的方法来实时识别其毛细血管扩张和脑中心的环境信息，对于工程应用来说，期望人类听觉信号处理算法能够适用于回波定位机制的研究。
