AB  - The state-of-the-art passive methods for estimating the trajectory of a moving acoustic source involve computing the cross-correlation function either directly or indirectly (as in the case of the Beam Forming Approach) between pairs of microphones. Also there have been several Active Acoustic techniques such as SONAR, RADAR, etc., which have been used to estimate the source parameters such as velocity, trajectory, etc. They involve pinging the source with a known signal. In this paper, given the fact that the moving source itself generates a signal, we propose a technique by which we estimate the source trajectory using only the signal captured at the receiver thereby avoiding the need to ping the source and without computing the cross-correlation function.
