Abstract:

For Global Navigation Satellite System (GNSS) receivers, adaptive antenna arrays are the most effective techniques for interference suppression. Unfortunately, adaptive antenna arrays may distort the GNSS signals and induce measurement biases on both code phase and carrier phase, which are unacceptable for precision applications. In this paper, the measurement errors induced by space-time anti-jamming algorithms are analyzed separately under the premise that the antennas and antenna electronics are ideal. Firstly, the sources of measurement errors are derived from the perspective of equivalent filter, the impact of measurement errors on position solution are analyzed. Additionally, a zero-biases constrained space-time anti-jamming algorithm is proposed. Simulation results demonstrate the effectiveness of the proposed algorithm.
