将非圆MUSIC(NC-MUSIC)算法与共形圆柱阵列相结合，分析了高性能的二维波达方向(DOA)估计。为了分析NC-MUSIC算法在实际应用中的性能，给出了共形阵列中各微带天线的实际辐射方向图。仿真结果表明，NC-MUSIC算法比标准MUSIC算法具有更高的分辨率，最大估计次数也有所增加。NC-MUSIC算法在不考虑天线影响的情况下，实现了较高精度的二维DOA估计。
Non-Circular MUSIC (NC-MUSIC) algorithm with a conformal cylindrical array is included to analyze high performance 2-D Direction of Arrival (DOA) estimation. The actual radiation pattern of each microstrip antenna in the conformal array is introduced to analyze the performance of NC-MUSIC algorithm in practice. The simulations show that NC-MUSIC algorithm has a higher resolution than the standard MUSIC algorithm, and the maximum estimation number of NC-MUSIC algorithm is increased, too. In spite of the influence of antennas, NC-MUSIC algorithm achieves 2-D DOA estimation accurately.
