Doa estimation exploiting coprime arrays with sparse sensor spacing
Yimin Daniel Zhang, Si Qin, Moeness G. Amin · 2014
In this paper, we propose effective coprime array configurations in which the minimum interelement spacing is much larger than the typical half-wavelength requirement. Such configurations are important in many applications where the half-wavelength requirement cannot be met due to the physical sensors size or to avoid spatial oversampling in wideband operations. The application of such coprime arrays in direction-of-arrival estimations is examined using different algorithms.
