Echolocation and acoustic communication in bats 回声定位蝙蝠及其声通讯
The echolocation of bats is a major field in the research of bats 蝙蝠回声定位的研究一直是国际上蝙蝠研究的重点和热点。
Utilization of artificial neural networks in the identification of bats ' echolocation calls 人工神经网络在蝙蝠回声定位叫声识别方面的应用
Presently the way of study the echolocation calls of bat is localizated in traditional fourier analysis 目前对蝙蝠回声定位信号的研究方法主要局限于传统的傅立叶分析。
Dwt is testified to be a new effective way in analyzing the echolocation signals of bats 因此,小波分析是分析蝙蝠回声定位叫声的一种有效的新途径,有其广泛的应用价值。
Many bats emit an echolocation call that contains a narrow frequency range and then analyze returning echoes to navigate and to detect prey 许多蝙蝠会发出频率?围狭窄的回声定位呼叫,然后分析回声来作导航与侦测猎物。
When ben was 3 , he began teaching himself echolocation , something he picked up by tossi ng objects and making clicking noises to find them 班恩三岁时,就自学回声定位,他丢掷物体再藉由发出舌音去找那些东西,这样就学会了。
So it is very meaningful to study their echolocation calls in ecology concentrates in researching time - frequency charaters of the signals 根据调研我们知道,从生态学角度对蝙蝠的叫声研究多集中在对信号本身的时频特性研究。
