The radiation efficiency of short electric dipole and small magnetic loop is low. Therefore, the long electric dipole and large magnetic loop for direction of arrival (DOA) estimation are investigated in this study. A novel array composed of long electric dipole, large magnetic loop, or a hybrid long electric dipole and large magnetic loop is proposed. Then a corresponding algorithm based on ESPRIT is proposed to estimate the two-dimensional (2D) DOA. The proposed array has eight elements. The first four elements and other four elements construct the rotational invariant property. Then, the 2D direction cosine can be estimated accurately but with ambiguity. After that, the ambiguous value is instituted into the spatially spread vector sensor for spatial phase compensation. Then, the steering vector of the collocated orthogonal vector sensor is obtained to calculate a fake coarse DOA estimation. By comparing the above ambiguous fine estimation with the fake coarse estimation, the closest estimation is taken as the finally 2D DOA estimation. The computation of the proposed algorithm is small due to a lack of angle searching. Moreover, the long dipole has high radiation efficiency, and the spatially spread vector sensor has low mutual coupling. Simulation results demonstrate the effectiveness of the proposed algorithm.

短电偶极子和小磁环的辐射效率低。因此，在这项研究中研究了长电偶极子和大磁环的到达方向（DOA）估计。提出了一种由长电偶极子，大磁环或长电偶极子与大磁环混合组成的新型阵列。然后提出了一种基于ESPRIT的算法来估计二维（2D）DOA。建议的数组包含八个元素。前四个元素和其他四个元素构成旋转不变性。然后，可以准确地但不确定地估计2D方向余弦。之后，将模糊值设置到空间扩展矢量传感器中以进行空间相位补偿。然后，获得并置正交矢量传感器的转向矢量，以计算伪造的粗DOA估计。通过将上述模棱两可的精细估计与伪造的粗略估计进行比较，将最接近的估计作为最终的2D DOA估计。由于缺少角度搜索，所提出算法的计算量很小。此外，长偶极子具有高辐射效率，并且空间扩展矢量传感器具有低互耦合。仿真结果证明了该算法的有效性。长偶极子具有高辐射效率，而空间扩展矢量传感器的互耦性低。仿真结果证明了该算法的有效性。长偶极子具有高辐射效率，而空间扩展矢量传感器的互耦性低。仿真结果证明了该算法的有效性。
