TIME-DOMAIN ANALYSIS OF A REFLECTOR ANTENNA ILLUMINATED BY A GAUSSIAN PULSE
Keywords:Asymptotic methods, time-domain, reflector antennas
In this work the asymptotic Time-Domain Physical Optics and Time-Domain Uniform Theory of Diffraction are applied to the analysis of a hyperboloidal reflector antenna illuminated by a Gaussian pulse to illustrate their applicability. The results are compared with those obtained by a reference integral-equation formulation, in order to specify the limitations of the time-domain formulations.
