Abstract
Techniques are provided for tracking of signals. A methodology implementing the techniques according to an embodiment includes filtering a first segment of an input signal, associated with a first time interval, into a first plurality of frequency bins. The method also includes detecting a signal of interest (SOI) in one of the first plurality of frequency bins. The method further includes filtering a second segment of the input signal, associated with a second time interval, into a second plurality of frequency bins. The method further includes determining movement of the SOI from a first frequency bin, of the first plurality of frequency bins, to a second frequency bin, of the second plurality of frequency bins. The method further includes tracking the SOI based on the movement determination. In some cases, the method further includes creating a composite signal based on the tracking over multiple frequency bins and multiple time intervals.
