The conventional decoherence methods based on the uniform circular array are generally affected by the array model errors. To solve this problem, we proposed a new algorithm based on array rotation and translation method. By rotating and translating the dual antenna array to form multiple virtual UCAs, the proposed algorithm can achieve multi-targets direction estimation of coherent signals. The simulation results show that the new algorithm has better robustness on multi-channel gain-phase errors, and it can realize the direction of arrival estimation of coherent and independent signals at the same time.
