The satellite signal is spread-spectrum signal,and the power is 20~30 dB lower than noise of receiver,it is jammed easily.Study of the the jamming ability of satellite navigation receiver is important.Eigen-space decomposition algorithms is an effective adaptive anti-jamming algorithm.A basic model for array signal is built first.The theorem of array signal eigen-space decomposition is introduced.The performances of algorithms are analyzed.At last,the validity of algorithms is proved by the computer simulation.
