Review of measurement methods for the main reflection surface of radio telescope antennas
Abstract
<p indent="0mm">The accuracy of the main reflector surface is one of the most significant factors influencing radio telescope performance. Thus, research on and application of main reflector surface measurement are an important foundation for evaluating and compensating the antenna performance. In this review, theodolite measurement, laser measurement, holographic measurement, photogrammetry, and sensor measurement are assessed, and the principles and application cases of each measurement method are explained and summarized to offer a reference for the main surface measurement technology of QTT.</p>
