利用双端口网络和天线散射方程的几何解释，可以推导出在适当设计的散射测量中可以确定天线特性。作为一种替代方法，它表明增益和辐射方向图的测量程序可以从天线的接收、发射和散射特性的简单考虑中发展出来。该技术的主要优点是不需要增益标准，并且可以避免对天线的干扰馈线。除此之外，这项技术似乎非常准确。在标准增益角上的实验数据很好地证实了这些一般结论。概述了误差来源，并与传统技术中的误差来源进行了比较。
Using a two-port network and geometrical interpretation of equations involved in antenna scattering, it can be derived that antenna characteristics may be determined in properly designed scattering measurements. As an alternative to this approach it is shown that measurement procedures for gain and radiation pattern can be developed from simple considerations of the receiving, transmitting, and scattering properties of antennas. The main advantages of the technique are that no gain standard is required and a disturbing feedline to the antenna can be avoided. In addition to this the technique seems to be highly accurate. These general conclusions are well corroborated by experimental data on a standard gain horn. Sources of errors are outlined and compared with sources of errors in conventional techniques.
