Novel method to evaluate the effectiveness of UAV navigation spoofing

In this paper, a novel evaluation method to evaluate the effectiveness of UAV navigation spoofing is proposed. The evaluation index system of UAV navigation spoofing effectiveness is proposed from three aspects: system device, spoofing signal and spoofing ability. According to the basic principles of navigation spoofing and the actual application requirements, the success probability criterion, scope criterion, spoofing precision criterion, spoofing power criterion and spoofing time criterion are selected. Based on the comprehensive method of hierarchy analysis and fuzzy evaluation, a reasonable evaluation model of UAV navigation spoofing effectiveness is constructed. Through simulation analysis of the effectiveness evaluation case of specific UAV navigation spoofing, the feasibility of the proposed evaluation method is validated.
