| 摘 要： | 本文基于3D立体线阵以及累量的灵活定义，实现了信号DOA的全方位估计，该算法不依赖于信号的具体结构，并构造了三个累量域DOA矩阵，通过对DOA矩阵的特征分解得到配对特征向量，从而获得信号DOA的全方位估计，该方法避免了2D或1D的谱峰搜索，仿真实验结果表明了这种方法的正确性。

| Abstract: | In this paper,based on 3D linear array and on the flexible definition of cumulant,a new method is proposed to achieve estimation of omnidirectional DOA The method does not depend on definite signal structure,and constructs three DOA matrixes in cumulant domain Pairing signature vectors are acquired via eigen decomposition of the matrixes and finally lead to estimation of omnidirectional DOA Moreover,the method can avoid 1D or 2D spectral peak searching Computer simulations make sure its availability |
