Effect of Gaussian feed cross-polarization on the cross-polar characteristics of tri-reflector compact antenna test range

An analytic model with different levels of cross-polarization for Gaussian feed is proposed to facilitate a general investigation of the cross-polarization in CATR's quiet zone. Simulation results based on GRASP are shown how different levels of cross-polarization of Gaussian feed affects the cross-polarization of the quiet zone in the proposed CATR.
