摘要

This paper analyzes the influence of the space-time signal processing technique on the performance of GPS signal acquisition in conditions of strong broadband interference (jamming) and multipath. The space-time processing method used for effective mitigation of GPS interference before processing by a conventional acquisition algorithm is the Minimum Variance Distortionless Response beamforming method with QR factorization (MVDR QR). The numerical results obtained by simulations demonstrate that many factors such as array configuration, number of array elements, and sampling rate of the incoming data have a considerable effect on the effectiveness of both beamforming and acquisition algorithms.
