本文主要介绍如何利用射电源来检测天线,这是一种简便而实用的方法。文中首先介绍一些射电源的辐射特性,然后讨论如何利用最强的射电源—太阳,来检测雷达天线,在检测时如何取得数据,及进行数据变换。文中还给出变换计算的详细步骤和具体应用实例。最后简要指出应用本法的优缺点。 This article describes how to use the radio source to detect the antenna, which is a simple and practical method. In this paper, we first introduce the radiation characteristics of some radio sources and then discuss how to use the strongest radio source, the sun, to detect radar antennas, how to obtain data during the detection, and to transform the data. The article also gives detailed steps to transform the calculation and application examples. Finally, it briefly points out the advantages and disadvantages of applying this law.
