A anti-jamming method for satellite navigation system based on multi-objective optimization technique

Abstract: In this paper, an anti-jamming method, which turns the single objective optimization problem into a multi-objective optimization problem by utilizing 2-norm, is proposed. The proposed jamming suppression method can reduce the wide nulls and wrong nulls problems, which are generated by the common adaptive nulling methods. Therefore a better signal-noise-ratio (SNR) can be achieved, especially when the jammers are close to satellite signals. It can also improve the robustness of the algorithm. The effectiveness … Show more

“…Characterizing and profiling the type of jamming affecting the communication link is the first step towards the deployment of an effective anti-jamming solution. Based on such considerations, the authors in [106], [109], [113], [114], [116], [118] proposed anti-jamming algorithms able to characterize the jamming signals emitted from multiple jammers and still guarantee the communication quality. In this context, it is worth mentioning the work by the authors in [115], mitigating jamming in SATCOM by proposing a costeffective solution able to thwart jamming through an efficient jamming-dependent adaptive frequency hopping pattern.…”

“…Many scientific contributions used physical layer parameters to estimate and guarantee the availability of downlink and uplink SATCOMs under jamming. For instance, to face malicious jamming attacks, the contributions in [98]- [100], [102], [109], [117] recommended the use of well-known techniques such as fast orthogonal search, signals cross-correlation, turbo codes, and distance theoretical models for the GPS signals. Alternatively, the authors in [102] demonstrate that the single-frequency multi-constellation receivers offer better jamming resilience than multi-frequency (L1 + L2) GPS receivers and that the GLONASS constellation demonstrated a better resilience than GPS.…”
