DOA Estimation for Generalized Three Dimensional Coprime Arrays: A Fast-Convergence Quadrilinear Decomposition Algorithm
In this paper, we construct the generalized 3-D coprime 275/60r15 mickey thompson array (G-TDCA) configuration, which consists of two 2-D uniform subarrays, by selecting three pairs of coprime integers to obtain the extension of inter-element spacing.Meanwhile, we derive the analytical expression of Cramer-Rao bound for G-TDCA and verify that G-TDC
