在已知静区场和被测天线口径场理论分布的基础上，建立了一种精确有效的数值模型，用于模拟在小型天线测试靶场（CATR）上测量的被测天线（AUT）远场。与AUT的理论远场模式的比较显示了预期的测量精度。数值模型考虑了静区内AUT的相对运动，并且对于静区和孔径场分别已知的任何CATR和AUT均有效。本研究中的受试天线是确认标准天线（VAST 12），过去专门设计用于天线测试范围确认。仿真结果以及真实的测量数据提供。
An accurate and efficient numerical model is developed to simulate the far field of an antenna under test (AUT) measured in a Compact Antenna Test Range (CATR), on the basis of the known quiet zone field and the theoretical aperture field distribution of the AUT. The comparison with the theoretical far-field pattern of the AUT shows the expected measurement accuracy. The numerical model takes into account the relative movement of the AUT within the quiet zone and is valid for any CATR and AUT of which the quiet zone and aperture field, respectively, are known. The antenna under test in this study is the Validation Standard Antenna (VAST12), especially designed in the past for antenna test ranges validations. Simulated results as well as real measurements data are provided.
