GPS signal anti-jamming based on dual-polarized antenna array

Abstract

Interference suppression is an essential work and has great influence on the stability of GPS receiver. In this paper, an improved adaptive method of joint polarization and spatial domain is proposed to suppress interference by using the dual-polarized information. Simulation results show that it can effectively mitigate the interference signals and does not require knowledge of the directions of desired sources so that it is suitable for navigation signal processing.
