摘要
Abstract
A novel algorithm that utilizes some nice properties of single value decomposition (SVD) and can simultaneously estimate the azimuths and frequencies of multiple narrow-band signals impinging on a ULA is presented. By minimizing the Frobenius norm of the error matrix, noiseless data matrix is approximated by a matrix of the same rank. Some matrix structures processed by ESPRIT-like method to estimate the unknown parameters are constructed based on narrow band assumption of the signals. The azimuths and the frequencies pair automatically. High resolution can be obtained.with small computational load.关键词
