Blind Joint DOA and Polarization Estimation for Polarization Sensitive Coprime Planar Arrays via a Fast?Convergence Quadrilinear Decomposition Approach
调查了极化面阵中的波达方向估计(Direction of arrival,DOA)与极化估计问题,并提出了一种快速收敛的四线性分解算法.具体来说,首先把互质面阵分解为两个均匀面阵并利用传播算子算法得到了初始的方向矩阵估计.然后,将接受信号置于四线性模型,利用四线性交替最小二乘来估计所有可能的DOA与极化估计结果.接着,根据互质解模糊的原理,从所有的结果中提取出真正的估计值,消除了模糊估计结果.对比于传统的四线性交替最小二乘算法,本算法可以在不损失…查看全部>>
The problem of joint direction of arrival (DOA) and polarization estimation for polarization sensitive coprime planar arrays(PS-CPAs) is investigated,and a fast-convergence quadrilinear decomposition approach is proposed. Specifically, we first decompose the PS-CPA into two sparse polarization sensitive uniform planar subarrays and employ propagator method(PM)to construct the initial steering matrices separately. Then we arrange the received signals into two…查看全部>>
