提出了一种基于互高阶累积量的阵列宽带高分辨测向方法,该方法能够在较低信噪比、等间距布阵条件下实现宽带空间信号源波达方向的高分辨估计,同时可增加检测信号源数目,理论分析及仿真实验证实了该方法的有效性。

[Abstract]
In this paper, a high order cross cumulants based on antenna array DF method with wide frequency band and high resolution had been given. Based on the high order cross cumulants, a wide freuqency band and high resolution estimation can be realized in the condition of lower SNR and equal distance between the array eelements. And at the same time the detected signal number can be increased. The analyzing on theory and demonstrating indicated that the method is effective.
