一种联合利用方位多路径的TMA方法

A TMA Method of Jointly using Bearing and Multi-path Information

为了更好地利用大孔径基阵所获取的信息,提高TMA方法的收敛速度和估计精度,把大孔径基阵划分为两个子阵,提出了一种在修正极坐标系下联合利用方位/多路径信息的双子阵TMA方法,并与双子阵纯方位TMA方法的性能进行了仿真比较,验证了该方法的有效性和可行性。

In order to make better use of the information obtained by the large aperture array,and improve the convergence speed and the precision of the target motion analysis,this paper proposes a method which divides the large aperture array into two sub-arrays,and uses their target bearing and multi-path information based on modified polar coordinate. Compared with the two-bearings TMA method,the effectiveness and feasibility of the method are verified.
