摘要
噪声干扰器是水面舰艇非常重要的反鱼雷水声对抗器材。研究了噪声干扰器对鱼雷主动声呐的对抗原理,以等间隔直线阵为例,分别给出了干扰器对鱼雷主动声呐主瓣和旁瓣的干扰方程。仿真表明,干扰器能有效干扰鱼雷主动声呐,显著降低鱼雷主动自导作用距离,研究成果可为舰艇水声对抗装备发展以及作战使用方法等研究提供理论参考。
Noise-jammer is a kind of important acoustic countermeasure device, the principle of noise-jammer against active sonar of torpedo is researched. Based on uniform line array, the sonar equation of active sonar beam main lobe and side lobe interfered by noise-jammer are presented. Simulations show that noise-jammer can decrease the active homing guidance range of torpedo remarkably.
