Sufficient Conditions for Aliased Free Direction of Arrival Estimation in Periodic Spatial Spectra
The problem of broadband spatial spectral estimation with a uniform linear array where the interelement spacing is greater than a half-wavelength over the frequency band of interest is addressed. It is shown that by using properly chosen frequencies, ambiguities in the source location estimates can...
