摘要
Abstract
With the increasing number of frequency equipment on the ground,the electromagnetic jamming of satellite communication is becoming more and more serious.The large level jamming entering from the beam sidelobe will cause great harm,resulting in the decrease of the signal-to-jamming-noise ratio of the received signal and the inability of demodulation of the information.In order to solve this problem,a jamming cancellation method based on sum difference beam with simultaneous angle estimation is proposed.On the one hand,the incoming wave direction of the jamming is estimated by sum and difference beam;on the other hand,based on the estimation results,weighted summation of the received signal of the sum and difference beam is used to eliminate the jamming entering the system from the sidelobe.The simulation experiments prove that the proposed method can effectively suppress the sidelobe jamming of geostationary orbit(GEO)satellite ground station.It can maintain good performance under low signal-to-noise ratio and strong jamming conditions,and the interference suppression effect reaches more than 50 dB.关键词
