Abstract 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 mainfold 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 soucres.Simulations are presented with comparison to coherent signal-subspace method (CSM).
