Phase Compensation for Unconstrained GNSS Adaptive Array Processing
ICNC-FSKD(2019)
摘要
In order to maintain the phase continuity of GNSS signals for unconstrained adaptive array processing, we proposed a phase compensation method in this paper. The proposed method makes full use of the repetitive structure of the GNSS coarse acquisition (C/A) code to estimate the phase errors of GNSS signals introduced by array processing, and then the carrier phase is compensated by adjusting the corresponding numerically controlled oscillator (NCO). Compared with traditional methods, it is effective when more than one GNSS satellite signal is present. Simulation experiment is performed to verify its performance.
