| 摘 要： | 本文利用四阶累量的信息设计出约束最小冗余线阵，并提出了基于四阶累量的约束最小冗余线阵的ESPRIT波达方向估计方法．该方法具有以下特点：能够检测高斯加性噪声中的非高斯信号；突破了ESPRIT方法所要求的阵列构造，阵列孔径利用率高，可以用较少阵元估计出更多信号源的波达方向。本文最后给出的模拟实验验证了该方法的有效性。

| Abstract: | In this paper , restricted minimum redundant linear arrays are designed by fourth -order cumulants of signals first . Then a new method of DOA estimation using ESPRIT with the arrays having been designed is presented . The method has following merits . It can detect non-Guassian signals in additive Guassian noises . And it doesn't require the array configuration of ESPRTF and has higher utilization ratio of arrays ' aperture , so it can estimate more sources with fewer sensors. |
