| Abstract: | Due to the problem that satellite navigation signals are easy to be interfered,the anti-jammingtechnology based on space-time adaptive beam-forming is researched.The effect and compensation method ofsatellite signals from space-time processing is analyzed from the field of space and time respectively.The space-time adaptive beam-forming technology is simulated,and the results show that it can reach 8 5.dB interference tosignal ratio of anti-jamming capability,which validates the proposed technology. |
