Anti-jam adaptive array instrument for the weak GNSS in the fast time-varying scenario

The article introduced the structure and technology method of the anti-jam instrument based on the adaptive arrays theory for the weak GNSS. The different algorithms is transformed into the uniform GSC program structure which can contribute to saving hardware cost and improving the code's efficiency. To meet the need of the fast time-varying scenario, the multistage Wiener filter is introduced. Analysis and numerical experiments show that it is an effective method, especially in the fast time-varying scenario.
