摘要
由于柱面共形天线阵所具有的特殊性质,使得其在利用经典MUSIC算法进行DOA估计时,性能会受到较大影响。通过将柱面共形阵划分为多个子阵的方法,可以有效地解决此类问题。仿真结果表明,该方法能应用于柱面共形阵的DOA估计,并容易推广到任意曲面共形阵。
Because of special characters of cylindrical conformal array, the performance will be deterioration when using MUSIC algorithm to estimate signal＇s DOA of these arrays. The problem is efficiently solved by dividing a cylindrical conformal array into several subarrays. Simulation results demonstrate the proposed scheme can be used in cylindrical conformal array and any other curve conformal arrays for DOA estimation.
