摘要：Direction of Arrival Estimation and monitoring the animals is one of the crucial examine focuses in our Acoustic Sensor Network. Using hyperbolic c ircular 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 aco ustic signal by 3Kms and each sensor node deployed circularly 360 o deg by TOP, BOTTOM, LEFT, RIGHT hyperbolic arrangement. The sensor hardware circuit audio recording and playback using Atmega Microcontroller Schematic Arduino On - Board Interfaces are sup ported for recording elephant signals are illustrated with its pin diagrams in the following chapters. The experimental results focus on analysis of signal recei ving from base station and estimation of random error difference
