摘要：

In this paper, we present an efficient strategy for satellite signal acquisition in the presence of strong interferences. A GNSS receiver equipped with a fully augmentable non-uniform linear array is assumed. The interference directions of-arrival (DOAs) are estimated using a low-complexity and accurate Fourier-based approach. Interference suppression is then performed by placing nulls in the estimated directions. Using simulated data, the performance of the proposed scheme is compared with that of beamforming, root-MUSIC algorithm, and Minimum Output Power polynomial rooting method in terms of execution time, DOA estimation accuracy, and output signal-to interference-plus-noise ratio.
