An improved algorithm based on the symmetric uniform linear array (ULA) and the second-order statistics (SOS) is proposed to cope with the mixed far-field and near-field sources localization problem. The direction-of-arrivals (DOAs) and powers of far-field sources can be firstly estimated from the MUSIC spectral function. Then, an oblique projection technique is adopted to eliminate the obtained far-field...
Numerous studies for non-circular signals are being conducted to improve the performance of systems. However, the studies of Non-Circular MUSIC (NC-MUSIC) method include mostly uniform linear arrays and not as much effort has been devoted to other configurations. This paper extends the Non-circular MUSIC for the rectangular array. The simulation shows the NC-MUSIC method has a higher resolution and...
