基于改进模糊综合法的雷达抗干扰效能评估

现代战场上的电磁环境日趋复杂,雷达的抗干扰能力已经成为衡量整个雷达系统乃至电子对抗装备性能优劣的重要指标之一。针对模糊综合评估法在雷达抗干扰效能评估中对各指标隶属度不敏感的问题,受“木桶效应”启发,基于对效能评估指标体系中各指标隶属度值的奖励与惩罚机制,构造了局部状态变权函数对常权向量进行变权。在此基础上,提出了一种改进的模糊综合评估方法。最后,将该评估方法应用于雷达抗干扰效能的评估实例中,结果表明,使用该模型可以获得更加客观合理的评估结果。

Evaluation of radar anti-jamming efficiency based on improved fuzzy comprehensive method

The electromagnetic environment on the modern battlefield is becoming more and more complex, and the anti-jamming capability of radar has become one of the important indicators to measure the performance of the entire radar system and even the electronic countermeasure equipment. Aiming at the problem that the fuzzy comprehensive evaluation method is not sensitive to the membership degree of each index in the evaluation of radar anti-jamming effectiveness, inspired by the "Cannikin Law", based on the reward and punishment mechanism for the membership degree value of each index in the effectiveness evaluation index system, this paper constructs a local state variable weight function performs variable weight on the constant weight vector. On this basis, an improved fuzzy comprehensive evaluation method is proposed. Finally, the evaluation method is applied to the evaluation example of radar anti-jamming performance. The results show that more objective and reasonable evaluation results can be obtained by using this model.
