摘要：
An auxiliary antenna array scheme for sidelobe interference cancellation of satellite communication system is proposed in this paper. Considering earth curvature, signal bandwidth, and transmission loss, a precise model of satellite communication interference scenario is established. In order to improve anti-interference capability, the performance of the auxiliary antenna array is studied by the minimum mean square error (MMSE) criterion. Then, a 7-unit linear microstrip antenna array is manufactured as the auxiliary antenna array. The main contribution of this paper is the corresponding auxiliary antenna array analysis and design. Simulated and experimental results confirm that the proposed scheme can achieve a relatively high interference cancellation radio (ICR) of about 25 dB in a wide beam range.
