摘要

A theoretical model for array patterns of variable inclination continuous transverse stub (VICTS) antenna is proposed. The theoretical model is utilized to reveal the nonlinear relationship in beam scanning between the angular position of beam and the rotation angle of the radiation layer. A dynamic coordination system is used to simplify the theoretical model and reduce errors. Based on the dynamic coordination system, array pattern of VICTS antenna with arbitrary amplitude distribution and arbitrary aperture shape can be calculated by the theoretical model. Both the full-wave simulations and computation of the theoretical model are carried out. The calculation errors of the angular position of beam between the proposed method and the full-wave simulation are less than 1o. By using the proposed method, the problem of nonlinear and dynamic beam steering in the VICTS antenna servo control system can be solved.
