In this paper, a novel robust design algorithm based on estimation of signal steering vector and covariance matrix is developed. The theoretical covariance matrix is first estimated via the shrinkage method. Subsequently, the desired signal steering vector is estimated based on maximizing array output power under the correlation coefficient constraint and norm constraint. The original nonconvex quadratic programming problem, whose relaxation is tight through analyzing thehidden convexity properties, can be solved by the relaxed semidefinite programming method. Moreover, the interference-plus-noise covariance matrix is estimated with the corrected steering vector and thesubspace theorem, whose efficiency is analytically proven. Numerical experiments show that the proposed algorithm has the advantages of high efficiency and accuracy.
