摘要 通过子阵分割和虚拟内插技术在圆柱共形阵上实现了快速准确的来波方向估计。在此过程中,共形于金属柱体表面的圆环阵被划分为八个相同的子阵,每一个子阵通过内插,变换为虚拟均匀直线阵,应用旋转不变参数估计技术(ESPRIT)算法和Root-MUSIC算法,可以快速准确地估计出来波方向。仿真结果证实了该方法的有效性。 Sub-array divided and interpolated technique are used for DOA estimation on a cylindrical conformal array.A circular array mounted on a cylinder surface is divided to eight identical sub-arrays,and each sub-array is transformed to visual uniform linear array by interpolated technique.Using rotational invariance techniques（ESPRIT）and Root-MUSIC algorithm,direction of arrivals can be estimated accurately and efficiently.Validity of this method is verified by simulation results.
