大型高分辨率射电望远镜几乎不旋转,因此测量天线方向图是一项挑战。本文提出了一种基于相关技术和全球卫星导航系统(GNSS)的大型无线电天线方向图测量方法。利用辅助天线和无线电天线中导航信号的相关特性估计电场的归一化方向图函数。该方法避免了获取大量准确的伪码信息。与传统的基于能量检测的方法相比,该方法扩大了测量范围,提高了天线方向图的测量精度。同时,该方法在抗信道变化和抗干扰方面也具有较好的性能。
It is a challenge to measure the antenna pattern of a large-sized radio telescope with a high resolution because it hardly rotates. This letter presents a simple and efficient method to measure the large-sized radio antenna pattern based on correlation techniques and the Global Navigation Satellite System (GNSS). We estimate the normalized pattern function of the electric field by utilizing correlation properties of the navigation signal in the auxiliary antenna and the radio antenna. The method avoids obtaining a large number of accurate pseudo-code information. Compared to the traditional methods based on the energy detection, the proposed method extends the measurement range and improves the measurement accuracy of the antenna pattern. At the same time, the method also has a better performance in anti-variation of channel and anti-interference.
