Abstract
A method for improving spectral sampling using Discrete Fourier Transforms in a processor to detect a continuous wave (CW) signal in a burst having large initial uncertainties comprises the steps of dividing the burst into smaller sub-bursts; performing a Discrete Fourier Transform on each sub-burst; and non-coherently combining each sub-burst. A further variation includes selecting an optimal number L of sub-bursts based upon system performance, and desired detection performance at a minimum operating signal to noise ratio.
