为了提高天线远场方向图的测量速度，提出了一种压缩传感方法。天线方向图被扩展为球谐函数，从而提供了场的稀疏表示。然后，与传统方法相比，可以使用现成的算法来从减少的样本数量重建场。如各种实验示例所示，该策略可显著节省测量点的数量。
A compressive sensing approach is proposed to speed up the measurement of antenna far field patterns. The antenna pattern is expanded into spherical harmonics providing a sparse representation of the field. Readily available algorithms can then be used to reconstruct the field from a reduced number of samples compared to conventional approaches. This strategy leads to important savings in the number of measurement points as shown in various experimental examples.
