基于综合权重的鱼雷电磁引信抗干扰评估方法

摘要

针对鱼雷电磁引信对不同类型干扰的抗干扰能力无法进行定量评估的问题,提出了一种基于综合权重的抗干扰评估方法.该方法定义了峰值电压因子、包络持续时间因子、有效能量因子、信噪比因子和相似性因子5个评估指标,并利用组合权向量的方法对主观权向量和客观权向量进行综合得到最优权向量.仿真表明:提出的方法可以实现任意干扰对鱼雷电磁引信干扰能力的定量评估,且评估结果与实际相符.%Aiming at the problem that it was difficult to quantitatively evaluate the anti-interference performance of torpedo electromagnetic fuze under different kinds of interferences, an anti-interference evaluation method based on synthetic weight was put forward. Five evaluation indexes such as peak value factor, envelop duration factor,effective energy factor, SNR factor and comparability factor were defined in this paper. The subjective weight vector and objective weight vector were synthesized by combination assigning method and the best synthetic weight vector was obtained. Simulation showed that the proposed method could evaluate interference performance of torpedo electromagnetic fuze quantitatively,and the evaluation result corresponded with the practical situation.
