Abstract

The signals of Global navigation satellite system (GNSS) are susceptible to wideband RF interference. Polarized Pattern Constrained Minimum Variance algorithm (PCMV) is proposed to mitigate the interference and retain signal when interference and signal incident in the same direction. Due to polarization sensitive characteristics of dual-polarized array, the DOA and polarization of interference are estimated by TLS-ESPRIT algorithm. PCMV is to constrain the polarized pattern ratio between signal and interference so that the beam towards signal and the null towards interference are achieved in the respective polarized pattern simultaneously. Simulation with a 7-elememt array shows that array using PCMV can form nulls towards interference while form main beam towards signal even when the signal and interference are in the same direction.
