摘      要：Space-time interference suppression technique shows great predominance compared with other anti-jamming techniques. LCMV（Linearly Constrained Minimum Variance） criterion is often used in space-time adaptive processing. Beaming steering and null steering methods were deeply analyzed on LCMV criterion. A new space-time anti-jamming method is proposed combining beam steering and null steering. The method reduces the signal loss of satellite signal DOA estimation error compared with beaming steering and improves the output SINR compared with null steering. Numerical simulation demonstrates that the proposed method is effective and efficient.
