Abstract:

Power spectral estimation provides one approach to direction finding. This approach readily generalizes to produce a collection of newer direction finding algorithms. Estimation of the bispectrum yields a bispectral direction finder. Estimates of time-frequency distributions produce Wigner-Ville and Gabor direction-finders. Some types of non-stationary time series admit spectral estimators which can be used to localize a source. Chaotic signals can also be localized using recently developed parameter estimators.
