摘 要:自适应调零天线能有效提高卫星导航接收机的抗干扰性能。本文介绍了功率倒置自适应调零天线的数学模型,分析了该技术的性能特点,并进行了抗干扰算法仿真,仿真结果发现:功率倒置自适应调零天线能抑制多个干扰信号,大大提高了卫星导航接收机的抗干扰能力,具有十分重要的应用价值和广阔的发展前景。The adaptive nulling antenna can efficiently improve anti-jamming performance of satellite navigation receivers. This paper introduces the mathematical model of adaptive nulling antenna based on power inversion algorithm. The functional characteristics were analyzed, and anti-jamming algorithm was simulated. The simulation results show that several interferences can be restrained by power inversion adaptive nulling antenna, which can remarkably improve the anti-jamming capability of satellite navigation receivers. The adaptive nulling antenna has important application value and development prospect.
