%X A novel method to estimate DOAs of coherent sources impinging on an uniform circular array(UCA) is presented in this paper. A virtual uniform linear array(VULA) is first derived by DFT preprocessing, transforming the UCA from element space to phase mode space which is special for circular arrays, and then the well-known spatial smoothing technique is applied to the VULA so that the decreased rank of covariance matrix due to coherence can be retrieved. Simulation results have strongly verified the effectiveness of the algorithm.
