Digital detection and tracking of signals over multiple frequency bins

A computer program product including one or more non-transitory machine-readable mediums encoded with instructions that when executed by one or more processors cause a process to be carried out for receiving a signal of interest (SOI), the process comprising:

• filtering a first segment of an input signal into a first plurality of frequency bins, the first segment associated with a first time interval;
• detecting the SOI in a first frequency bin of the first plurality of frequency bins;
• filtering a second segment of the input signal into a second plurality of frequency bins, the second segment associated with a second time interval;
• determining movement of the SOI from the first frequency bin to a second frequency bin included in the second plurality of frequency bins, wherein the first frequency bin is different from the second frequency bin;
• and
• tracking the SOI based on the movement determination.

A method for receiving a signal of interest (SOI), the method comprising:

• filtering, by a processor-based system, a first segment of an input signal into a first plurality of frequency bins, the first segment associated with a first time interval;
• detecting, by the processor-based system, the SOI in a first frequency bin included in the first plurality of frequency bins;
• filtering, by the processor-based system, a second segment of the input signal into a second plurality of frequency bins, the second segment associated with a second time interval;
• determining, by the processor-based system, movement of the SOI from the first frequency bin to a second frequency bin included in the second plurality of frequency bins, wherein the first frequency bin is different from the second frequency bin;
• and
• tracking, by the processor-based system, the SOI based on the movement determination.
