abstract = "In satellite navigation system with low signal-to-noise ratio (SNR), array anti-jamming antenna usually adopts power-inversion (PI) adaptive anti-jamming algorithm to suppress interference. In order to improve the anti-jamming performance of array antenna, a PI algorithm based on matrix eigendecomposition is studied according to the characteristics of array covariance matrix. This algorithm solves the problem of ill-conditioned matrix caused by low SNR of array received signal and overcomes the shortcoming of the open-loop algorithm of direct matrix inversion in hardware implementation, which has a complex structure and a large amount of computation. The simulation results show that the algorithm has a remarkable effect on the suppression of strong interference, high precision of weight vector and fast updating speed. In addition, the implementation structure of high-performance anti-jamming system based on PI algorithm in FPGA is analyzed.",
