中文摘要：
提出了一种基于FIR滤波器的时域宽带矩阵空域滤波器设计方法。首先，采用窄带矩阵空域滤波器优化设计方法，设计对应工作频带内各子带的恒定扇区响应空域滤波加权矩阵集。应用该矩阵集元素重构Ⅳ个宽带基阵加权向量集，设计对应的N个恒定响应空域宽带FIR滤波器，进而构成时域宽带矩阵空域滤波器。该方法实现了对阵元接收宽带数据的时域矩阵空域预滤波，提高了系统的实时信号处理能力。计算机仿真和实验数据处理结果验证方法的有效性。
英文摘要：
A designing method of time-domain broadband matrix spatial pre-filtering was investigated. Firstly, the matrixes of matrix spatial pre-filter for frequency bins were deduced by optimal-designing-method. Secondly, the volumes of all weighting matrixes corresponding to the same output were put together to construct N groups of weighting vectors. Then, spatial broadband FIR filters corresponding to group of weighting vectors were designed. Finally, these N spatial broadband FIR filters were synthesized to construct the time domain broadband matrix filter. Using it, element-data can be spatial pre-filter in time-domain. So it can improve real-time probability of system. Results of simulation and lake-experiments verify the approach developed.
