  • 基于非相干信号子空间(ISM)的宽带源DOA估计方法
    首先分析了基于非相干信号子空间(ISM)的宽带源DOA估计方法,并将基于数 据阵共轭重构的修正MUSIC算法应用于ISM方法中,提高了分辨能力而且可以分 辨相干信源。接下来讨论了相干信号子空间(CSM)方法的宽带相干源DOA估计, 分析了聚焦矩阵及聚焦频率对DOA估计性能的影响,给出了最佳聚焦矩阵的选择 标准和最佳聚焦频率的选择方法。 针对色噪声环境下宽带信号的波达方向估计,研究了将传播算子思想应用于 TCT聚焦矩阵的相干信源DOA估计新方法。该方法基于传播算子思想,直接利用 阵列接收信号估计噪声相关矩阵,得到一种快速TCT聚焦矩阵。从而提高了色噪声 环境下宽带信号DOA估计的性能,传播算子的应用避免了TCT算法中复杂的特征 分解,降低了运算量。通过计算机仿真证明了新方法的有效性和可行性。 关键词: 宽带阵列信号 波达方向估计 色噪声 信号子空间 聚焦矩阵(DOA MUSIC)
