Evaluation of antijamming performance for infrared guidance system based on improved analytic hierarchy process

To address the issues of strong subjectivity and arbitrariness in weight assignment within the traditional Analytic Hierarchy Process (AHP), this study proposes an anti-jamming performance evaluation method for infrared guidance systems based on theoretical analysis and grey correlation. First, a hierarchical evaluation index system is established. The impact of the evaluation index system on the anti-jamming performance of infrared guidance systems is analyzed, distinguishing between quantitative and qualitative evaluation indicators. For quantitative indicators, objective weights are derived by constructing a judgment matrix using the proportion of influence degree. For qualitative indicator parameters, expert opinions are collected using the 1–9 scale method, and expert weights are assigned via the grey correlation method, with simulation verification conducted to validate the approach. This approach provides valuable insights for evaluating the anti-jamming performance of similar infrared guidance systems.
