Abstract :
A method of antenna pattern reconstruction using sampling field data in sparse grid of points in Fresnel zone is presented. According to this method, antenna far field pattern in a desired section is reconstructed from several sections of the field in Fresnel region. Fresnel field to far field transformation is based on two-dimensional Fourier series expansion. Main features of the method are discussed. Computer simulation results are given.
