| 摘 要： | 本文提出了一种新的基于信号空时特征结构的高分辨二维DOA估计方法-时空DOA矩阵方法.该方法在保持原DOA矩阵方法无需二维谱峰搜索和参数配对等优点的基础上,利用阵元输出之间的互相关关系将空域的阵列观测数据变换到时空域,通过空时二维处理在时空域中衍生出大量虚拟阵元,从而大大减弱了传统方法中对阵列结构、排布方式和阵元一致性的约束,不需要匹配子阵,无冗余阵元与孔径损失,并适用于阵元排列不规则的阵列.仿真结果证明了该方法的有效性.

| Abstract: | In distributed fusion system,the problem that sensors of the system are of different type is a widespread problem.In this paper,from the process of hierarchical fusion,a resolution of fusion state definition,dimension extension of filter state vector from a single sensor as well as its covariance matrix,trace fusion and prediction after extension is introduced,followed by the essence of such kind of problem. |
