标题： Multipath-Enhanced Measurement of Antenna Patterns: Theory

摘要： 传统天线方向图测量涉及在测量环境中尽量减小多径传播的影响。 相反，本文介绍了一种测量方法，该方法利用多径传播而非抑制它。 这被称为多径增强天线方向图（MEAP）测量技术。 在这方面，该方法与多输入多输出（MIMO）系统有一些相似之处。 在MIMO系统的情况下，优势是增加了容量；而在MEAP方法中，优势是无需创建消声环境。 该方法使用参考天线的测量来校准多径信道矩阵，并使用矢量球面谐波进行高效的方向图表示。 在介绍了该方法的数学细节之后，给出了说明该方法的数值计算结果。 实验结果在一篇配套论文中进行了描述。 显示英文摘要

摘要： Traditional antenna pattern measurements involve minimizing the impact of multipath propagation in the measurement environment. In contrast, this work introduces a measurement approach that uses rather than mitigates multipath propagation. This is referred to as the Multipath-Enhanced Antenna Pattern (MEAP) Measurement technique. In this respect the approach has some kinship with Multiple-Input Multiple-Output (MIMO) systems. The advantage in the case of MIMO systems is increased capacity; in the MEAP approach the advantage is elimination of the need for creating an anechoic environment. The approach uses measurements with reference antennas to calibrate the multipath channel matrix, and vector spherical harmonics for efficient pattern representation. After presenting the mathematical details of the method, numerical calculations illustrating the approach are presented. Experimental results are described in a companion paper.
