| 摘 要： | 给出了一种在高斯白噪声环境下对多个窄带信号进行二维波达方向估计的新方法.该方法根据给出的天线阵列结构的特点,首先构造四个相关矩阵,进而构造一个大的矩阵,对其进行一次特征值分解,由ESPRIT原理实现了信号波达方向的准确估计.该方法精度较高,不存在错误估计,有一定的实用性.

| Abstract: | Based on an three-dimensional array,a novel method for estimating two-dimensional direction of arrival(2-D DOA)for multiple signals in Gauss noise is proposed.The array geometrics are employed by the algorithm to calculate the four coherent matrixes which are used to construct a special large matrix,then the signal subspace estimation is obtained via the eigende composition of the constructed matrix,and the DOA is achieved precisely by ESPRIT method.The simulated results show that this method is characterized by high precision,no failure and good practicability. |
