在许多情况下，天线测试范围内的反射构成了设施级误差预算内最大的单个分量[1]。一段时间以来，一种名为数学吸收反射抑制(MARS)的频域测量和后处理技术被成功地用于减小球面近场和远场天线测量系统中的距离多径效应[2，3，4]。最近，已经开发了一种用于柱面近场天线测量系统的相关技术[5，6]。本文介绍了测量技术和新的测头方向图校正近场到远场变换算法。然后介绍了正在进行的验证活动的最新结果，详细说明了一些最新的进展，这些进展被发现产生了与相应的球形火星技术相媲美的改进。对结果进行了讨论，并给出了结论。
In many instances, reflections within antenna test ranges constitute the largest single component within the facility-level error budget [1]. For some time, a frequency domain measurement and post-processing technique named Mathematical Absorber Reflection Suppression (MARS) has been successfully used to reduce range multi-path effects within spherical near-field and far-field antenna measurement systems [2, 3, 4]. More recently, a related technique has been developed for use with cylindrical near-field antenna measurement systems [5, 6]. This paper provides an introduction to the measurement technique and novel probe pattern corrected near-field to far-field transform algorithm. It then presents the most recent results of an ongoing validation campaign detailing a number of the most recent advances which are found to yield improvements comparable to those attained with the corresponding spherical MARS technique. The results are discussed and conclusions presented.
