本文给出了多基元扇形柱面基阵指向性函数,分析了其比较复杂的相位特征。详细阐述了通过合理选取基元数目、加后挡以及振幅权重等方法有效的抑制旁瓣,以实现对声信号方位跟踪及目标定位。
In this paper, the directivity function of the multi-cell fan-shaped cylindrical array is given, and its more complicated phase features are analyzed. It elaborates that the sidelobe can be effectively suppressed by reasonably selecting the number of the elements, adding the backstop and the amplitude weight, so as to realize the azimuth tracking and the target location of the acoustic signal.
