摘要：
Recently, nested array has been proposed to estimate the direction of arrival (DoA) of O(N-2) sources using only O(N) physical sensors. In this paper, we investigate a new method to achieve higher degrees of freedom for the nested array for non-circular sources. By exploiting the properties of the signal sources, a new model is constructed based on a longer virtual uniform linear array (ULA). Simulation results show that the proposed method can identify more sources with N sensors and improves the DoA estimation accuracy.
