%X A fast direction-of-arrival (DOA) estimation algorithm is proposed that applies to coherent wide-band emitter signals impinging on an uniform linear array. This algorithm, where spatial smoothing technique is employed, is based on obtaining the array manifold of a desired narrow-band covering the center frequency of the whole wide-band. The fast algorithm, which has super-resolution, leads to the realization of real-time bearing estimation of multiple coherent wide-band sources. Simulations are presented with comparison to coherent signal-subspace method (CSM).
