Multi-beam anti-jamming method for satellite navigation signals based on dynamic clustering

In response to the anti-jamming requirements of satellite navigation, multi-beam anti-jamming technology based on adaptive beam forming is studied. In order to solve the problem that the traditional fixed multi-beam anti-jamming method cannot consider all the navigation satellite signals to reduce the receiving performance when the number of beams is limited, a dynamic multi-beam anti-jamming method based on the K-means clustering algorithm is proposed. The antenna array is established for simulation, and the results show that the anti-jamming performance of this method is better than the traditional method when the number of Beidou satellite signals received is more than the number of beams.
