A method of detecting a signal (S) of interest contained within a waveform (F) comprised of a plurality of signals within a frequency spectrum, as well as random noise. After first detecting the waveform, a determination is made as to whether the duration (Td) of the waveform is sufficient for subsequent processing. If the duration is not sufficient, the waveform is concatenated with itself to produce a waveform of sufficient duration. The concatenated waveform is then processed and the results supplied as an input to an oscillator (24) operating at a nominal output frequency. The oscillator cancels the effects of noise in the waveform and the frequency of the oscillator shifts to a different frequency which is a function of the signal of interest. The shift in output frequency of the oscillator is detected and analyzed to obtain the signal of interest. The oscillator can be either a general purpose oscillator or a Van der Pol oscillator.
