| 摘 要： | 为了提高波达方向(Direction of Arrival,DOA)估计的性能,提出一种虚拟借助旋转不变技术估计信号参数的时空矩阵(Virtual Estimating Signal Parameters via Rotational Invariance Techniques-Time Spatial Matrix,VE-SPRIT-TSM)算法。即利用两行均匀直线阵构造出三组子阵列,并根据由此得到的数据估计用户的二维DOA。理论分析表明,该算法可提高了阵列的利用率,计算误差更小,并能改善DOA的估计性能。计算机仿真实验证明该算法有效。

| Abstract: | In order to improve the performance of DOA(Direction of Arrival),a VESPRIT-TSM(Virtual Estimating Signal Parameters via Rotational Invariance Techniques-Time Spatial Matrix) algorithm is presented.By This algorithm,three subarrays can be constructed from a double-row uniform linear array,which is based on to figure out some new data used for 2-D DOA estimation.It can be proved that,this algorithm raise the utilization rate of the given array a lot,and makes less error than the original one.Simulation result... |
