Abstract
A new iterative procedure for estimating the direction of arrival of plane waves in the presence of noise with an unknown correlation structure can also be used to separate line spectra from a wide class of smooth spectra. It exploits the differences between the correlation structures of the generalized wavelet coefficients of the noise and signal processes. For simplicity of exposition, the procedure is explained in the context of the problem of localizing narrowband signal sources located in the far-field of a uniformly spaced linear sensor array. It can be applied as well to non-linear or non-uniform arrays and wideband signals.<>
