浅海中由 ODN 误调整引起的误动作一直是困扰某些鱼雷使用效果的重要问题。文中从 ODN 需要抑制的混响成分与波束指向性旁瓣两方面出发,分析了它们对 ODN 混响鉴频时机的影响,并以 MK46鱼雷为分析对象,定性、定量地验证了混响成分与波束指向性旁瓣对 ODN 中的影响程度,提出在浅海中应在发射声脉冲后有足够长的延迟后才能进行混响鉴频(采样),这样既可以避开波束旁瓣对 ODN 的误校准,又能准确测到主瓣混响的频率,保证 ODN 有最好的抗混响效果。 Mistakes caused by misalignment of ODNs in shallow seas have been an important issue plaguing some torpedoes. Based on the two aspects of reverberation components and beam-direction sidelobe (ODL) that need to be suppressed by ODN, this paper analyzes their influence on timing of ODN reverberation and takes MK46 torpedo as the analysis object to verify qualitatively and quantitatively that reverberation components and The influence of the beam-oriented sidelobe on the ODN suggests that the reverberation frequency discrimination (sampling) should be performed only after the acoustic pulse is emitted in the shallow sea, so as to avoid the error of the sidelobe of the beam to the ODN Calibration, but also accurately measure the frequency of the main lobe reverberation, to ensure that ODN has the best anti-reverb effect.
