Abstract :
This paper presents a new method for real-time tracking of target signal parameters in passive underwater acoustics. The method provides a recursive, closed-loop αβ tracking algorithm, in which gains α and β adapt automatically in a continuous-valued, instantaneous manner, to both received target signal-to-noise ratio variation, and target dynamical maneuvers.
