水声基阵声学隔板声屏蔽性能研究

摘要

针对水声基阵艉部噪声屏蔽问题,设计了一种新型复合结构声学隔板装置.在仿真计算的基础上,采用声学隔板和声基阵,组建了试验装置,应用水声换能器综合参数测试系统和声呐信号处理系统,在开阔水域对声学隔板屏蔽水声基阵的声场特性进行了试验研究.试验结果表明,设计的声学隔板对声基阵艉向噪声遮挡效果与计算结果相吻合,屏蔽角满足声基阵观察范围,验证了设计的声学隔板满足声基阵艉部噪声控制.%In this study, a new type of composite structure acoustic baffle was designed.This device was used in an underwater acoustic array stern noise shielding.The test device was designed on the basis of the measurements from the simulation.The acoustic characteristics of the underwater acoustic array shield possessing an acoustic barrier in open waters were studied with an underwater acoustic transducer parameter test system and a sonar signal processing system.The test results illustrate that the noise insulation effects and the shielding range are consistent with the cal-culation results.Additionally, the shielding angle is in accordance the observation range of the acoustic array. Thus, we verify that the acoustic baffle design achieves acoustic array stern noise control.
