Microwave Holography for Analysis of Diffraction.

Abstract

A method is described for determining the field distribution near a transmitting antenna. The method involves measurements over a spherical surface and computationally reconstructs the nearfields. The method is holographic because the complex conjugates of the measured field components are used. The method applies to planar or conformal arrays. Experimental results are given. Reconstructed nearfields are compared with measured values, and farfield patterns computed from the reconstructed nearfields are compared with measured patterns for several excitations of four element arrays.
