摘　　要：针对自适应调零天线对抗中的干扰效能评估问题,提出了层次分析评估法.首先,选取对抗效能评估指标,建立评估层次结构模型;其次,利用层次分析法给出对抗效能的评估方案;最后,利用3种经典自适应调零算法在不同空域干扰下的性能指标进行评估实验.实验结果表明,所提方法能够在不同自适应调零天线对抗实验方案中进行合理、有效的评估,具有较强的适应性.该研究不仅可用于调零天线对抗方案的优化及其干扰效能评估,而且也可指导调零天线抗干扰技术的改进.For the problem of evaluating countermeasure effectiveness against the adaptive nulling antenna, the evaluating method using the analytic hierarchy process （AHP） is proposed. First, evaluating indexes of countermeasure effectiveness are selected and the hierarchical structure model is established. Then, the method of evaluating countermeasure effectiveness is obtained by using the AHP. Finally, the performance indexes of three classical adaptive nulling algorithms are evaluated with various space jammings. The results of simulation show that the method can evaluate different countermeasure means reasonably and effectively, and it also has a strong adaptability. The research can be not only used in optimizing countermeasure means and their effectiveness evaluation, but also helpful for improving the anti-jamming technology of the adaptive nulling antenna.
