摘要
为了定量分析和评估鱼雷电磁引信接收机对欺骗式干扰的抗干扰能力,通过对鱼雷电磁引信目标特性及工作机理的分析,定义了抗干扰系数和幅值系数,给出了两者之间的计算关系式,并提出了以抗干扰系数作为评估指标的定量评估方法。针对鱼雷电磁引信接收机中典型的滤波电路和时间检验电路,利用电路分析法推算了二者的幅值系数,进而推出其抗干扰系数。最后,利用抗干扰系数对鱼雷电磁引信接收机抗2种欺骗式干扰能力进行评估,其结果与实测一致,验证了本文所提出的评估方法的可行性与有效性。
In order to analyze quantitatively and evaluate the anti-interference capability of a torpedo electromagnetic fuze receiver against deceiving jammings,an anti-interference coefficient and an amplitude coefficient are defined by analyzing the target characteristics and working principle of torpedo electromagnetic fuze,and the relational expression of the two coeffi-cients is derived.Moreover,a quantitative evaluation method is put forward taking the anti-interference coefficient as an evaluation index.According to the typical filter circuit and timing test circuit in torpedo electromagnetic fuze receiver,their amplitude coefficients are calculated by using the circuit analysis method and their anti-interference coefficients are reckoned.The anti-interference capability of a torpedo electromagnetic fuze receiver against two deceiving jammings is evaluated with the anti-interference coefficient,and the result coincides with the measurement,which validates the feasibility and effective-ness of the proposed method.
