摘要
基于阵元数差一的两个平行均匀线阵组成的信号接收系统提出了多个空间窄带信号源频率和到达方向二维参数估计的高分辨率快速方法。方法的参数估计是直接计算的，避免了二维空间中的谱峰搜索和信号源之间的参数配时，实时性较强。计算机模拟结果证实了此方法的有效性。
Based on signal received system consisted of two parallel uniform linear arrays whichelement number diffirence is one,a new method for estimating spatial signal frequencies and directions ofarrival of multiple narrow-band signals is proposed in this paper.Without any spectral peak search on thetwo-dimension space and perameter pairing among signals,the resulting method not only is compationallyefficient with high resolution and fast speed,but also be processed in the parallel way.Computersimulation experiments demonstrate its effectiveness.
