Modified Woodward synthesis method and application to design the feed of large aperture antennas

  • Received Date: 23 Jun 2003

  • A new method of antenna directional pattern synthesis using least-squares or pseudoinverses is presented here ,which is based on the analysis of traditional Woodward-Lawson synthesis method and other modified methods. This new method combined with array beamforming technology is used to design the elementary directional pattern of large aperture antenna/FAST(five-hundred meter aperture spherical telescope). The number of samples can be either equal to or larger than the dimension of antenna arrays in this presented method.And there is no constraints in the synthesis areas.So the synthesized beamforming is much more flexible, and has much wider application situations.
