Abstract
An adaptive blind beam-forming algorithm based on array steering vector estimation is proposed to suppress interference signals received by the satellite navigation receivers. The received data are firstly projected to signal plus noise subspace to suppress strong interference in the first stage. Then the output data from the signal plus noise subspace are sent to carrier phase estimation modules, where each satellite navigation signal is tracked to estimate array steering vector. With the estimated steering vector, beams pointing to the direction of navigation satellites can be formed. Simulation results show that the proposed algorithm is valid for interference suppression in presence of interference, and the anti-jamming performance is much better than the power inversion (PI) algorithm and maximum carrier to noise ratio (MCNR) with three successive integrations.
