Experimental Study of the Scattering Properties of Microwave and Millimeter-Wave Horn Antennas Using the Inverse Aperture Synthesis Technique

Аннотация

We use the technique of two-dimensional inverse aperture synthesis to study experimentally the radio images formed by microwave and millimeter-wave horn antennas. The radio images, which have a resolution of about a wavelength corresponding to the center of the operating frequency range of the studied horns, allow one to describe clearly the mechanisms of structural scattering of the horns and estimate numerically the contribution of such mechanisms to radio images.
