摘要

Adaptive array signal processing is widely used to improve anti-jamming capability for satellite navigation receivers. Robust beamforming approaches based on steering vector uncertainties, which have been proposed in recent years, have better performance than standard minimum variance distortionless response (MVDR) beamformer in space adaptive processing (SAP). In some practice applications, the attitude of antenna array varies with vehicle attitude, so beam pointing should be timely adjusted with vehicle attitude. Vehicle attitude aided space-time adaptive beamforming approach has been proposed for moving vehicle. Every visible satellite was allocated a beam independently. The anti-jamming capability of these robust beamforming algorithms were evaluated in space-time domain and ultra low signal-to-interference plus noise ratio (SINR) environment. The simulation results show that these robust beamforming algorithms have no superiority over standard MVDR beamformer in anti-jamming performance. Hence, the attitude aided space-time MVDR beamformer can be used to mitigate interferences with less computation in navigation receiver.
