摘要

针对循环平稳信号，提出了一种广义的传感器阵列数据模型，并提出了一种基于加权循环频谱的到达角估计方法——GSC-SSF。该算法在数据矩阵或协方差的形成上更方便有效。矩阵为MUSIC或ESPRIT算法估计AOA和抑制噪声。仿真结果表明，该方法具有较好的性能。

Angle-of-arrival estimation based on weighted cyclic spectrum

For cyclostationary signals, a generalized sensor array data model is presented and a new angle-of-arrival (AOA) estimation method based on weighted cyclic spectrum - GSC-SSF is developed in this paper. The proposed algorithm is more convenient and effective in forming the data matrix or the covariance. matrix for the MUSIC or ESPRIT algorithm to estimate AOA and suppress noise. Simulation results show better performance for the new method.
