Impact of Jamming Attack on Galileo Receivers

This paper surveys the impact of different jammers on the Galileo receivers in L1 band. Specifically, we exam the relationship of the sweep-rate of chirp-style jammers with the detection probability when acquiring a Galileo signal. The simulation results show that the relationship between the sweep-rate of the chirp jammers and the resulting impaction of the acquisition process is a non-linear function. With the C/N0 of 45 dB-Hz, the probability of successful acquisition is less than 95% when the sweep rate of the chirp jammer is about 1GHz/sec and the jamming-to-signal ratio (JSR) is above 21 dB, on the other hand, when the jammer type is of the continuous-wave interference, the Galileo receivers can tolerate the JSR of 25 dB.
