  • 从平面近场扫描数据处理原理和平面天线阵方向图理论出发, 分析了相对于平面近场扫描平面斜置的平面天线阵方向图.基于斜置平面天线阵的空间结构关系, 选择阵面旋转轴与阵面法线形成的平面为性能评估考察平面,发展了一种快速计算性能评估平面方向图的方法.得出该平面与平面近场扫描坐标系单位方向球相交曲线的轨迹参数方程. 利用快速傅里叶变换技术,计算出斜置平面天线阵平面近场扫描空间方向图, 在此基础上结合轨迹参数方程和二维插值方法解出对应该性能评估平面的方向图数据. 数值仿真和实际应用结果表明该分析结论和方法的可靠性与实用性.
    Based on the principle of planar near-field measurement and theory on the spatial pattern of planar antenna arrays, a comprehensive investigation on the spatial pattern of planar antenna arrays tilting away from the planar near-field scanning plane is performed. An efficient computational algorithm on the near-field-far-field pattern in the plane determined by the rotation axis and normal line of the tilted array is developed. The parametric equations on the intersecting curve locus between the plane and unit directional sphere of the planar near-field scanning are thus derived. Consequently, the spatial pattern of the tilted antenna array based on the near-field data is calculated by fast Fourier transform technique, and at the same time a two-dimensional interpolating scheme to evaluate the pattern in the plane is developed. The capability, efficiency, and feasibility of this new algorithm are demonstrated by the good consistency of the calculated results with the numerical simulations and experimental measurements.
