N2 - The BeiDou Navigation Satellite System (BDS) is widely used in various fields such as military and civilian. However, the low transmit power and high spatial attenuation make the satellite navigation signal with very little power when it reaches the ground receiver, completely submerged in thermal noise, and vulnerable to intentional or unintentional interference, resulting in the degradation of the receiver's positioning performance or even the inability to locate. For the situation that the BeiDou navigation receiver cannot be positioned normally due to broadband suppression interference. In this paper, a space-time interference suppression model is established based on a four-element antenna, and then the space-time adaptive algorithm based on power inversion is analyzed and simulated. The simulation results show that the space-time adaptive anti-jamming algorithm based on power inversion can effectively improve the receiver's ability to suppress wideband interference and narrowband interference.
