摘要：
A direction of the arrival (DOA) estimation method utilizing polynomial rooting is developed for monostatic MIMO radar. Utilizing the redundancy of the received data, a reduced-dimensional matrix is firstly performed to alleviate the temporal snapshots requirement and the computational burden resulting from the inversion of the covariance matrix. To further alleviate the complexity burden, a polynomial rooting method is proposed to identify the extreme values of Capon spatial spectrum. Since the target DOA lies in the set of all extreme values, DOA estimation method can be performed based only on the candidate angles around those extreme values. Numerical results verify the effectiveness of this method. (C) 2010 Elsevier B.V. All rights reserved.
