Method and Verification of Interference Suppression for Beidou Satellite Forwarding Based on Array Antennas

The article focuses on the inherent characteristics of Beidou satellite navigation signals being susceptible to interference, especially when subjected to forward deception interference, which can cause errors in receiver positioning results. Adopting a forward interference recognition method based on satellite signal suppression, innovatively utilizing attitude information to assist and suppress satellite signals to identify forward interference. By simulating and analyzing the situation of inaccurate attitude information assistance or using low-cost inertial navigation in alternating flickering interference scenarios and virtual interference simulation, the results show that this scheme can generate strong nulls in the direction of interference and effectively identify and suppress interference, The receiver can maintain normal positioning.
