摘要
Abstract
For the direction of arrival (DOA) of coherent signals, a new algorithm based on covariance matrix reconstruction named TSV-ESPRIT was proposed. The signal eigenvectors including the direction information of all sources was used to construct the Toeplitz covariance matrix. This construction method is without reducing the array aperture and increase esti⁃mation resolution and stability. The estimation of signal parameter via rotational invariance techniques (ESPRIT) instead of multiple signal classification (MUSIC) was used to avoid the peek searching and reduce the computational complexity. Sim⁃ulation results and analysis proved the validity and effectiveness of the algorithm.关键词
