A Surveying Method of Muti-Function Corner Reflector for SAR Antenna

SAR (雷达干涉测量)是现在较为新的测量方法，其具有全天性、全天时等测量特点，已经很好的应用在各个方面。对于SAR，反射角的标定测量精度是非常重要的。本文阐述角反射器的定位原理，对室外标定时水平放置、检校场标定时天顶放置两种状态下的精密定位测量方案进行研究，研究其测量顶点内角坐标的方法，并得到很好的效果，对其他人员起到借鉴作用。 SAR (Synthetic Aperture Radar) is a relatively new method of measurement. It can be used in every day and every time of the daytime, and so on and it has been well applied in all kinds of aspects. For SAR, it is very important to measure the accuracy of the calibration. The positioning principle of the muti-function corner reflector is described in this paper, precision positioning measurement method under two conditions: horizontally placed field setting and zenith placed calibration field standard setting is also studied. Besides, we also measure the method of MYS vertex coordinates, and obtain good effects, which could be a reference for other people.
