Abstract

Adaptive beamforming based on the oblique projection technique, which can maximum retain useful signal and form nulls in the interference direction. The oblique projection technique is applied to GPS anti-jamming with good effect. GPS satellite signal is very weak, at the same time, the steering vector of the satellite signal is difficult to obtain. these make the oblique projection technique difficult to apply to GPS anti-jamming. Aiming at this problem, this paper proposes a low-complexity subspace tracking algorithm for acquiring GPS satellite steering vectors based on the cyclostationary characteristics of GPS satellite C/A codes. Simulation experiments results demonstrate of this algorithm.
