Abstract :
A novel DOA estimation for uniform circular arrays (UCAs) in correlated environment is proposed, which is based on the array virtual translation. Instead of transforming the steering vector of a UCAs to one with Vandermonde from, or interpolating, in the new approach the subarrays is designed by a virtual translating of the original array, then the MUSIC algorithm is employed to estimate the desired directions, the VT-MUSIC approach for short. Simulation results strongly verify the high performance of this approach
