Abstract
A method for signal detection including the steps of: (1) iteratively acquiring sets of signal samples in a time domain N times; (2) iteratively applying a first transform to each iteratively captured samples in the time domain to convert each set of samples in the time domain to a corresponding subsequent set of samples in a frequency domain; (3) iteratively creating array rows using each of the sets of samples in the frequency domain wherein each subsequent array row has a length N; (4) appending each subsequent array row to the array until a second axis representing time reaches length N; (5) applying a second transform to the array to create a plurality of layers of spectral content; (6) determining a location of a signal of interest within the array based on a threshold; and (7) applying a bounding box to the array to isolate the signal of interest.
