摘要：小型天线测试范围（CATR）的成功设计和实现取决于高精度和精密计算电磁（CEM）建模工具的可用性。由于这些模型的准确性对CATR的设计和后续设施级不确定性预算的确定至关重要，因此本文提出了五种不同的CEM模拟的准确性评估。我们报告了CATR建模方法的结果，包括：几何光学与几何衍射理论、平面波谱、Kirchhoff-Huygens和电流元，然后介绍了它们在给定CATR组合的远场天线方向图测量预测中的应用结果。
Abstract—The successful design and implementation of a compact antenna test range (CATR) is predicated upon the availability of highly accurate and precise computational electromagnetic (CEM) modelling tools. As the accuracy of these models is paramount to both the design of the CATR and the subsequent determination of the facility level uncertainty budget, this paper presents an accuracy evaluation of five different CEM simulations. We report results using methods of CATR modelling including: geometrical-optics with geometrical theory of diffraction, plane-wave spectrum, Kirchhoff-Huygens and current element, before presenting results of their use in the farfield antenna pattern measurement prediction for given CATRAUT combinations.
