| 摘 要： | 提出了一种基于高阶累积量的信号频率和二维角估计算法。假设阵列中存在3个特性完全一致的阵元，此时使用高阶累积量实现的阵列虚拟展宽相当于存在两个和实际阵列相同的虚拟平移阵列，因而在其它阵元位置和响应特性未知的情况下也能实现空间信号频率和二维角估计。推导了使用PRO-ESPRIT算法实现联合估计的过程，并给出了相应的信号配对方法，计算机模拟结果证实了该算法的有效性。

| Abstract: | In this paper, we discuss a new cumulants-based method for the joint estimations of frequencies and 2D-DOAs of spatial signals. By providing three identical sensors in the array, the extension of the array through cumulants can be viewed as two virtual displaced copies of the real array. So we can estimate the frequencies and 2D-DOA with arbitrary geometry array by ESPRIT. The PRO-ESPRIT is used and the matching rule of the estimated parameters is proposed correspondingly. The simulation resiults demonstrate the effectiveness of the method. |
