Direction-of-arrival (DOA) estimation in the presence of gain-phase errors for uniform-circular-array (UCA) is addressed in this paper. Thanks to the uniformity and cycle property of UCA, the long data vector constructed with the proper entries of the Hadamard product of autocorrelation matrix and i...
