摘要：

The minimum variance distortionless response (MVDR) beamforming technique and space-time adaptive processing (STAP) have been playing important roles in interference suppression of globe navigation satellite system (GNSS) receiver. However, the demand for conformal arrays is increasing these days and its characteristics will vitiate the traditional MVDR method. And on the other side, traditional MVDR based on STAP will inevitably distort the Beidou signal, which is unacceptable in high precision GNSS applications. To address the above issues, first, a conformal array signal processing model is proposed; and based on that, a distortionless MVDR method is proposed in this study. The simulation results show that the proposed method can not only suppress the interference better than the traditional MVDR, but also guarantee the Beidou signal to be undistorted.
