摘要

提出了一种利用近场球面测量获得高精度远场图的新技术。提出的技术是基于场映射算法，它提供精确的场在任何所需的表面上从近场数据测量平面，圆柱，或球面。这种方法使计算完整的远场方向图成为可能，特别是包括大型反射天线的背景波。

Spherical near-fîeld measurements for electrically large antennas

A new technique is presented for highly accurate far-field patterns obtained from spherical measurements in the near field of electrically large antennas. The proposed technique is based on the Field Mapping Algorithm, which provides exact fields on any desired surface from near-field data measured over a planar, cylindrical, or spherical surface. This method makes it possible to calculate complete far-field patterns, including especially the backlobes for large reflector antennas.
