WAN Qun, YANG Wan-lin. Approach for Direction of Arrival Estimation with Sensor Gain Uncertainties[J]. Acta Electronica Sinica, 2001, 29(6): 730-732.DOI:
Recent studies have shown that performance of MUSIC or other algorithms degrades drastically and even fails with a bad knowledge on array manifold.An approach based on 1-dimensional searching for DOA estimation with unknown intensity coefficients was presented in [1].The ambiguous peaks appearing in certain cases must be eliminated.In this paper
a new method based on generalized eigenvalue decomposition is proposed.Detailed analysis of ambiguous problem is presented and is illuminated by numerical examples.
