基于AHP-PCA的雷达导引头抗干扰能力评估方法

Anti-jamming performance evaluation method for radar seeker based on AHP-PCA

摘要:

多专家评价是评估雷达系统抗干扰能力的传统有效手段，但存在不同专家水平高低、偏好不同引起的评价失准问题。该文将层次分析法(AHP)与主成分分析法(PCA)相结合，提出了保证多专家群体决策一致性的AHP-PCA方法。将AHP-PCA运用于雷达导引头抗干扰能力评估，得到不同专家对于同一环境下的导引头系统抗干扰能力评价的综合结果，并定量描述该综合评价结果的群体决策一致性。结果表明AHP-PCA方法可以减少评价失准问题的影响，降低由于专家偏好不同导致的评价的主观性，具备工程应用价值。

Abstract:

Multi-expert evaluation, as a traditional and effective method to evaluate the anti-jamming capability of radar systems, has the disadvantages of inaccurate evaluation caused by differences of expert levels and individual preferences. In this paper, by combining Analytic Hierarchy Process(AHP) with Principal Component Analysis(PCA), an AHP-PCA method is proposed to ensure the consistency of multi-expert group decision-making. The comprehensive results about the anti-jamming capability of the seeker system in the same environment are obtained through the application of AHP-PCA to the anti-jamming capability evaluation of radar seekers. Then the consistency of the group decision on the comprehensive evaluation results is described quantitatively. The evidences suggest that the AHP-PCA method can reduce the impact of evaluation inaccuracy and the subjectivity of evaluation caused by different preferences of experts, and that AHP-PCA is of engineering application value.
