摘要
提出了一种基于四阶累积量和极化敏感阵列的近场源方位角、距离二维参数联合估计算法,其特点是采用非中心对称均匀线阵,无需参数配对,可直接计算出待估计参数的闭式解,具有较高的估计精度,可应用于加性高斯噪声环境,仿真试验证明了该算法是有效的.
The paper proposed a bearing and range parameters estimation algorithm of near-field sources based on four order cumulant and polarization sensitive array. The algorithm adopts non-centra-symmetric and non- parametric-match. It can directly calculate the closed-form solution of estimating parameter, and it has higher estimated accuracy. The algorithm can be used in additive Gaussian noise environments. The simulation results show the effect of this algorithm.
