Abstract
The problem of constructing a frequency tracker for weak, narrowband s ignals with slowly varying frequency is considered. An extended Kalman filter is proposed that uses prior knowledge of the nature of the sig nal to overcome the difficulties presented by the inherent nonlinearit y of the problem and the very low signal-to-noise ratios.
