【摘要】 低频噪声干扰器由于能对线导鱼雷的导引声呐进行有效干扰压制,在水声对抗中得到了广泛应用,但由于作战态势和战术使用较为复杂,干扰器的对抗效果很难评估。从理论上分析了低频噪声干扰器的作用原理;依据雷达干扰效果因素的概念,提出了基于干扰品质因素的效能评估方法;通过仿真手段给出了给定条件下低频噪声干扰器的干扰效果评估方法应用。该方法能较好地评估干扰器的对抗效果,为水声对抗系统中干扰器的战术使用提供了参考依据。更多还原

【Abstract】 In now underwater warfare,low frequency noise jammer(LFNJ)is widely used because of its effective jamming capability to thread homing torpedo’s sonar in enemy’s submarine,but campaign situation and the usage of LFNJ is very complicate,how to evaluate the countermeasure effect of LFNJ is become difficult.This paper first mainly analyzed the principle of the LFNJ,and then according to the concept of effect radar jammed,an evaluation method of LFNJ based on jamming quality factor is given,at last through simulation way,an implication of evaluation method of LFNJ is given under certain condition.This method provides a valuable reference for how to use LFNJ in underwater acoustic countermeasure system because of its better using effect.更多还原
