摘要
结合载体的姿态测量数据,采用GPS天线阵技术判别干扰,利用自适应算法调整天线阵的波束角以抑制、剔除干扰,从而提高了GPS动态实时定位的精度和可靠性,仿真结果表明,这种方法对不同方向的干扰信号都有较高的抑制比。
A method which conbined with the data of attitude surveying is proposed. The GPS antenna-array technology is used to differentiate the interferences, and the adaptive algorithm is used to eliminate interferences by setting zeros of antenna-array beam angle. The simulation indicates that this algorithm has high suppression on the jammers coming from different directions.
