Abstract
Direction of Arrival Estimation and monitoring the animals is one of the crucial examine focuses in our Acoustic Sensor Network. Using differential hyperbolic circular array the elephant vocalization Direction of Arrival is estimated with various external factors affecting Non-Line of Sight areas. In our experimental analysis each acoustic microphone array are seperated by 0.5M (mts) and circularly sensed the acoustic signal by 3 Kms and each sensor node deployed circularly 360o deg by TOP, BOTTOM, LEFT, RIGHT hyperbolic arrangement. The experimental results are carried out by MATLAB WAVE tool 8.1 and anaysed the overall accuracy of Direction of Arrival estimation for real time (96%) and simulated data 92% accuracy. The sensor hardware circuit audio recording and playback using Atmega Microcontroller Schematic Arduino On-Board Interfaces are supported for recording elephant signals are illustrated with its pin diagrams in the following chapters.
