| 摘 要： | 提出了一种无需参数配对的近场源距离、方位联合估计算法。该算法通过对构造的阵列输出信号四阶累积量矩阵,进行一定的变换构造处理得到一个新的矩阵,利用其相应的特征值及特征向量估计出二维参数。与ESPRIT-Like方法相比,文中算法参数估计结果能自动配对,而无需再进行配对过程。计算机仿真结果证实了提出方法的有效性。

| Abstract: | This paper presents a new method for joint estimation of ranges and directions-of arrival (DOA's) of multiple near-field sources without pairing parameters.A new matrix has been obtained from the transformation of the constructed four-order cumulant matrix.The parameters are directly given by the eigenvalues and eigenvectors of the new matrix.Compared with ESPRIT-Like method,the proposed method can achieve automatic pairing.Finally,simulation validates the performance of the proposed method. |

| Keywords: | near-field source cumulant DOA estimate range estimate automatic pairing |
