  • Based on fourth-order cumulant, this paper presents a new method, i.e. CTSS algorithm, for joint estimation of frequency and 2-D arrival angles of coherent signals. Firstly a time-space smoothing matrix is constructed by temporal and spatial data of two parallel uniform linear arrays and the smoothing technique, and then 3-D parameters of coherent signals can be obtained from its eigenvalues and the corresponding eigenvectors. In Gaussian colored noise, the algorithm can precisely estimate 3-D parameters of coherent signals, and does not need multidimensional spectrum peak search with 3-D parameters paired automatically. In addition, it can still estimate correctly 3-D parameters of signals when signals have the same one or two dimensional parameters. Computer simulation confirms its effectiveness.
