Abstract

Our paper focuses on the detection and direction finding of jamming signals in Global Navigation Satellite System (GNSS) bands. A methodology for in-lab validation for three selected jammer detection algorithms and two selected jammer direction finding algorithms is presented and measurement-based results, for nine combinations of GNSS and jamming signals, are shown. Both chirp jammers and amplitude-modulated single-tone jammers are considered in our in-lab validation process. The algorithm selection was done based on literature studies. Power-based detectors and direction finding algorithms are considered in this paper. It is shown that the considered detectors have similar performance and good detection probabilities for Jammer-to-Signal ratio (JSR) above −10 dB and that the Minimum Variance Distortionless Response (MVDR) beamformer can estimate quite accurately the jammer’s Angle of Arrival (AoA) with JSR above 10 dB.
