Abstract

In this paper, we implement real time specific target acoustic fingerprint for estimating Direction of Arrival (DOA) and Error Analysis at two different atmospheric conditions. The proposed DOA estimation method comprises of partial hyperbolic circular array for specific target generated random signal generation. The proposed sensor network consists of four nodes arranged in a circular array and all the n odes are Omni directional in nature. We test out proposed system for about circular ly covered around 3 Kms with two different forests for specific target (elephants) situated in India. DOA estimation is obtained by pre processing the random signal generat ed at forest using hyperbolic circular differentiation. In addition to DOA estimation, we are estimating the error analysis factors affecting outdoor propagation of sound in forests with different constraints
