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