Anti-jamming Performance Evaluation of GNSS Receivers Based on an Improved Analytic Hierarchy Process

The anti-jamming performance evaluation of global navigation satellite system(GNSS) receivers in complex electromagnetism environment is important. In order to analyze the anti-jamming capability of GNSS receivers in different interference scenarios, an anti-jamming performance evaluation method based on an improved analytic hierarchy process (AHP) is proposed. Firstly, the anti-jamming performance index of GNSS receivers is given by using the constraint of the minimum performance index. Secondly, the improved analytic hierarchy process evaluation model is obtained by using three scales instead of nine scales. Furthermore, the evaluation model is verified by using measured data, which realizes the quantitative anti-jamming performance evaluation of GNSS receivers. The experimental results show that the proposed method can improve the credibility of the anti-jamming performance evaluation results for GNSS receivers.
