Abstract: This paper provides array signal processing super-resolution fast algorithm. This algorithm based on the eigenvalue value shift of covariance matrix and its power iteration. It does not needs the inverse matrix. It converges quickly and only needs several iteration to converge to solution. Its architecture is very simple and easily implemented. -
