Abstract :
We present more information about improved methods for estimation of the frequencies of sinusoids which are closely spaced in frequency and which are observed in the presence of noise using limited apertures in time and/or space. We compare our realization of maximum likelihood estimation of multiple frequencies with an improved version of Owsley´s method and with the forward-backward prediction method advocated by Ulrych and Clayton and by Marple.
