在分析水下爆炸声源声学特性的基础上,研究了水下爆炸噪声对低频被动声呐的对抗机理,以圆柱形基阵为例,对不同水声干扰弹装药量、干扰弹到潜艇距离以及海况等级条件下对声呐主瓣、旁瓣的压制干扰效果进行仿真分析。结果表明,与传统噪声干扰器相比,水下爆炸声源对声呐的干扰效果更为明显,能显著降低声呐的探测距离,可为己方舰艇的机动规避和后续对抗创造有利条件。
Based on the acoustic characteristics of underwater explosive acoustic source(UEAS), the principle of underwater explosive noise against low-frequency passive sonar is researched. Taking an example of cylindrical sonar array, the interference effectiveness of sonar beam main lobe and side lobe interfered by acoustic interference source are simulated under different charge mass of underwater acoustic interference shell, distance of interference shell to sonar and level of sea state. The results show underwater explosive acoustic source have more interference effectiveness and can decrease the detective distance of sonar markedly compared with traditional noise-jammer, which provide advantages for evasion and subsequent countermeasures of own warship.
