| 摘 要： | 本文提出了一种用广义谱相关信号子空间拟合进行波达方向估计的方法,该方法同时适用于宽带与窄带信号的DOA估计,在窄带情形下还能够大大提高阵列的等效孔径.理论分析表明,目前几种主要的循环平稳DOA估计方法(如SC-SSF,Cyclic MUSIC,Cyclic ESPRIT)均可看作是该方法的特例或近似.最后,仿真结果证明了该方法的有效性与一般性.

| Abstract: | In this paper we propose a method called Generalized Spectral Correlation Signal Subspace Fining (GSC-SSF) for DOA estimation, which is applicable in both wide and narrow band scenarios. Especially, in narrow band cases, the method is capable of enlarging the effective aperture of sensor array considerably. It is proven herein that Several present DOA estimation method based on cyclostationarity including SC-SSF, Cyclic MUSIC and Cyclic ESPRIT are just the special cases or approximation of this method Its effectiveness and generality are illustrated by the simulation results. |
