| Research Abstract |
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.
