Abstract：In consideration of the typicality and generality of the horn as a wideband antenna, the paraxial wideband electromagnetic scattering characteristics of X-band standard gain pyramidal horn is studied. By using wide-band plane electromagnetic wave to irradiate the pyramidal horn antenna in shortcircuit state, a one-dimensional range microwave image is obtained based on monostatic frequency domain scattering data. The accurate intensity distribution of the antenna structural and mode scattering center is received from the imaging, and the scattering mechanism of the pyramidal horn is analyzed. And the effect of waveguide length and the polarization of the horn antenna are discussed, and a more holistic twodimensional microwave image is obtained with the angular domain scattering data. These results provide the most direct and useful information for the research of target characteristics of the pyramidal horn antenna and lay the foundation for understanding the scattering mechanism of horn antenna and other wide-band antennas.
