Evaluation Method of Satellite Navigation Spoofing Based on Power Feasible Region

  Objectives  In view of the difficulty of quantitative evaluation caused by complex spoofing scenarios and numerous anti-spoofing strategies, it is necessary to form effective indicators and methods for the evaluation of spoofing countermeasures.

  Methods  The evaluation model and mapping process from spoofing scenes to spoofing countermeasure effect are established. Based on the power space in the spoofing scenes and the spoofing effective probability in the spoofing countermeasure effect, the evaluation method and index based on the power feasible region are designed.

  Results  Through simulation, the quantitative evaluation results based on power feasible region of two spoofing countermeasure strategies are given, and the simulation results show that the evaluation method can realize the quantitative comparison of the performance of different anti-spoofing strategies.

  Conclusions  The indicator of the power feasible region can provide a quantitative evaluation method forselection and optimization of the anti-spoofing algorithms in receivers.
