| Quiet zone sampling is a powerful tool to evaluate the performance of a compact antenna test range. Such procedure consists of carrying out typically planar field acquisitions of the quiet zone. Acquired data yields valuable information about the measurement capabilities of the range under consideration. However, the required amount of samples increases quadratically with frequency for full 2D acquisitions. In practice, millimeter wavelength assessment of CATR facilities implies extremely time-consuming acquisition campaigns in addition to intrinsic mmwaves challenges, such as strict mechanical tolerances in construction and alignment, and high sensitivity to environmental factors. In this communication, we will focus on the CATR facility at ESTEC. A time-efficient acquisition technique has been developed and used to carry out millimeter wavelength quiet zone measurements between 46 ? 50 GHz. First tests of the technique show a high level of agreement between the results obtained with the proposed method and those corresponding to a classical Nyquist acquisition approach, while a time savings factor of about 8 is achieved. | |
