Abstract:	Space-Time Adaptive Processing (STAP) is an effective method to suppress the wideband interference in Global Navigation Satellite System (GNSS). However in high-dynamic environment, conventional STAP anti-jamming algorithms are invalid since jammer may easily move out of the array pattern null so that it cannot be suppressed. Null widening technique is an effective method to solve the above problem. STAP will not only increase the computational complexity significantly, but also require more training snapshots. Unfortunately, only few snapshots are available in high-dynamic environment. A novel high-dynamic wideband interference suppression method is proposed in this paper, which can reduce the computational complexity and achieve faster convergence speed simultaneously. Numerical results are provided to demonstrate the performance of the proposed algorithm.
