Abstract
A number of numerical techniques for fitting a sum of complex sinusoids to sampled correlation sequences are compared and it is shown that in the presence of slightly coloured noise all are roughly equivalent in performance but have differences in consistency with the original sequence. Fitting sinusoids directly to raw data sequences gives an accuracy equal to the Cramer-Rao lower bound for frequency estimation. The applications to direction finding in spatial arrays are discussed.
