  • METHOD AND SYSTEM FOR TIME DOMAIN ANTENNA HOLOGRAPHY
    Publication number: 20020158804
    Abstract: A fast, novel method is disclosed which permits to determine the electrical features of an antenna. The antenna is excited with an ultra-short voltage pulse and the far field radiation pattern of the antenna is measured. The resulting time-varying field distribution across the antenna aperture is then reconstructed using time domain holography. A direct analysis of the holographic plot permits the determination a wide range of electrical properties of the antenna.
