A Preliminary Analysis of Wireless Link for Bats Signals Acquisition System

Title variants
Languages of publication
The scope of an article that is presented below covers a preliminary analysis of a wireless link of ultrasound signal transmission in commercial radio frequency band (UHF). The radio link is used to transmit short ultrasound bat-like biosonar signals. Because of complicated structure properties and of transmitted signals the various methods of wireless transmission are shown. The hardware implementation consists of micro-electro-mechanical system microphone, microphone preamplifier and FM transmitter. At the end of the radio link a standard FM receiver is used. Since we use frequency modulation an influence of the radio link on received signal parameters is presented. The analysis of results provides us a set of information that might be used in designing of large scale wireless sensor networks for bats behavior monitoring.
