中文摘要:
      为提高潜艇对抗声自导鱼雷时机动方案的合理性,在高频噪声干扰器对抗声自导鱼雷原理分析的基础上,探讨了基于方位和能量的干扰效果分析方法。仿真分析了典型态势下噪声干扰器对主被动声自导鱼雷的干扰区域,给出了干扰扇面和自导距离缩减率随雷目距离的变化规律。结果表明,干扰噪声谱级比潜艇辐射噪声高出一定值(如15 dB)时,对被动声自导鱼雷具有较好的干扰效果,将宽带噪声功率集中到窄带中进行频率瞄准干扰,可大幅提高对抗主动声自导鱼雷的效果。该文的研究方法可为潜艇规避声自导鱼雷的机动方案提供依据。
英文摘要:
      To improve rationality of moving scheme for submarine countering acoustic homing torpedo, we analyze the basic theory of a high frequency jammer which counters acoustic homing torpedo, and give the interference effect analysis based on bearing and energy. In a typical underwater warfare we use numerical simulations to analyze the interfering area of the noise jammer, and give the varying rule of the jammer angle sector and the reducing rate of the torpedo homing range, which change with the range between the coming torpedo and the submarine. Theoretical analyses and numerical results show that when the spectrum level of the jammer noise is 15 dB larger than that of the submarine, it will effectively reduce the working range of the acoustic homing torpedo. And if using the frequency focusing interfering method (pouring the wideband power into the narrow one), the effect of countering the acoustic homing torpedo will be improved a lot. Our work in this paper can provide some supports for acoustic homing torpedo elusion tactic of a submarine.
