摘要
针对宽带相位干涉仪天线阵设计,提出一种基于相位差子矩阵和旋转矩阵的测向天线阵基线设计方法,通过构造相位差子矩阵,实现多阵元宽带相位干涉仪的高精度测向;并通过旋转矩阵选取最佳的天线阵元间隔,进一步提升测向精度。
A novel method for achieving the set of array spacing based on phase difference sub-matrix and rotation matrix is proposed to meet task requirement in the board-band phase interferometer.By constructing phase difference sub-matrix to realize high accuracy in the multiple array board-band phase interferometer.The optimum array spacing is selected through the rotation matrix,which improves the high direction-finding accuracy.
