An improved numerical procedure based on the Gabor series representation of the scattered field in front of a cylinder positioned in a focused beam system was used to reconstruct the scattering radiation pattern for plane wave illumination. The analysis was based on the assumption that the electric fields between the lenses can be described by fundamental Gaussian beams. The algorithm reduces significantly the required angular data measurements to reconstruct the scattering radiation pattern in comparison to a previous procedure based on an FFT algorithm. The information obtained on the scattering pattern helps to refine the calculations of the scattering analysis for large space frame radomes.
