摘　　要：针对全球导航卫星系统(GNSS)接收机抗干扰性能评估存在影响因素多、数据融合难的问题,提出了一种基于云模型的GNSS接收机抗干扰性能评估方法。该方法首先根据复杂电磁环境中的干扰因素建立接收机抗干扰性能评估指标体系,将其中的定性指标定量化后与定量指标共同构成云模型评估的依据;然后,采用黄金分割法建立接收机性能评价等级,利用云算法并结合指标权值计算各指标的云数字特征,得到直观的综合评价云;最后,通过计算云模型中综合评价云与各标准评价云之间的相似度大小获取最终评估结果,实现GNSS接收机抗干扰性能评估。与证据理论和模糊综合评估方法的对比结果表明,该方法可以实现对多个接收机抗干扰性能准确有效的评估,而且评估等级结果更加全面直观。In view of the problems that there are many influencing factors on anti-jamming performance evaluation of Global Navigation Satellite System(GNSS) receivers and it is difficult for data fusion,a novel anti-jamming performance evaluation method is proposed based on the cloud model.Firstly,the anti-jamming performance evaluation index system is established according to the interference factors in the complex electromagnetic environment.Moreover,the qualitative indexes are further converted into qualitative indexes, which form the basis of cloud model evaluation with other quantitative indexes.Then,the golden section method is used to establish the evaluation level of the receiver performance,and the cloud digital characteristics of the indexes are calculated by using the cloud algorithm and the index weights,through which the intuitive comprehensive evaluation cloud is obtained.Finally,the final evaluation results are acquired by calculating the similarity between the comprehensive evaluation cloud and each standard evaluation cloud in the cloud model,and the anti-jamming performance evaluation is thus completed.The results show that: Compared with evidence theory and fuzzy comprehensive evaluation method,the proposed method can implement accurate and efficient evaluation on anti-jamming performance of multiple receivers,and the results of evaluation level are more comprehensive and intuitive.
