一段时间以来，一种名为数学吸收体反射抑制（MARS）的技术已成功地用于识别并抑制球形[1，2，3，4]，圆柱形[5，6，7]和平面[8，9]近场天线测量系统中的距离多径效应。本文详细介绍了最近取得的进展，首次允许MARS测量和后处理技术被成功部署，以纠正使用直接远场或紧凑型天线测试范围（CATRs），其中只有一个大的圆形切割被收购的天线方向图数据。本文提供了一个概述的测量和新的数据转换和后处理链中使用的远场MARS（F-MARS）技术，以有效地纠正远场，频域数据。初步结果的范围内的测量，说明该技术的成功，并进行了讨论。
For some time now, a technique named Mathematical Absorber Reflection Suppression (MARS) has been used successfully to identify and then suppress range multi-path effects in spherical [1, 2, 3, 4], cylindrical [5, 6, 7], and planar [8, 9] near-field antenna measurement systems. This paper details a recent advance that, for the first time, allows the MARS measurement and post-processing technique to be successfully deployed to correct antenna pattern data taken using direct far-field or compact antenna test ranges (CATRs) where only a single great circle cut is acquired. This paper provides an overview of the measurement and novel data transformation and post-processing chain that is utilised within the far-field MARS (F-MARS) technique to efficiently correct far-field, frequency domain data. Preliminary results of range measurements that illustrate the success of the technique are presented and discussed.
