Abstract

The robustness of adaptive anti-jamming algorithms in a GNSS receiver will degrade in the presence of channel mismatch and antenna mutual coupling. In this paper, the effects of amplitude-phase errors and antenna mutual coupling on anti-jamming performance based on linearly constrained minimum variance (LCMV) algorithm with two different constraints are analyzed. Computer simulation results show the distinct extent of weakening in beamforming pattern and acquisition ability if different constraints are used.
