摘要：
This paper presents an algorithm for the far-field transformation of fields measured over linear cuts (slides) in planar measurement scenarios. Instead of scanning the complete plane, only two perpendicular slide measurements are performed, which reduces drastically measurement times. From these two measurements, the radiation pattern in the main cuts can be obtained, and then, the full 3D pattern is derived. The algorithm is based on particularizing the planar near-field to far-field transformation theory to a one-dimensional space. The proposed technique is presented and tested using simulated and measured data, showing low transformation errors and promising capabilities for the fast testing of antennas.
