摘要：

We have proposed a new multi-cut Fresnel-field to far-field transformation in the cylindrical scanning to overcome the error of an absolute gain pattern in a single-cut plane by using a single-cut near-field to far-field transformation. Because the multi-cut method requires the measurements on a several parallel cut-plates, we can obtain the 3D absolute gain pattern in a strip region between the several-cut planes. Therefore, the multi-cut method makes it possible to obtain the absolute gain patterns for any type of antennas and the peak absolute gain if the peak exists between the multi-cut planes. We demonstrate the effectiveness of the multi-cut method by simulations and the preliminary results using a EO probe at 76.2 GHz.
