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.
