摘要

<FONT face=Verdana>本文提出了一种无需参数配对的近场源距离、方位、频率联合估计算法。通过对构造的阵列输出信号四阶累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三维参数，无需谱峰搜索，算法适于任意高斯噪声环境。与现有算法相比，本文算法参数估计结果能自动配对，而无需再进行配对过程。最后，计算机仿真结果证实了提出方法的有效性。

Abstract

<FONT face=Verdana>A new method for joint estimation of ranges direction-of-arrivals(DOA’s) and frequencies of multiple near-field sources without pairing parameters is presented. 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 eigenvactors of the new matrix. Compared with several existing methods

the proposed methed can achieve automatic pairing. Finally

the simulation result are presented to validate the performance of the proposed method.
