矢量传感器在鱼雷被动声自导中的应用研究

在攻击目标采用各种隐身技术的条件下,提高水中兵器的有效探测距离是水中兵器研制工作中面临的重要课题。该文探讨了矢量传感器在鱼雷被动声自导中的应用,介绍了矢量传感器的组成及实现方法,设计了基于并行数字信号处理阵列机的硬件模块和相应的系统软件,并进行了系统联调和水池验证实验。实验结果表明,采用声压-振速组合传感器可以有效降低鱼雷自导系统的工作频率,减少信号的传播损失,从而增加自导系统的作用距离,提高方位估计精度。

Application of Vector Sensor to Torpedo Passive Homing Detection

The frequency in passive acoustic detection is usually high,which leads to a narrower detection range of undersea weapon.In order to enlarge detection range,the vector sensor,which can work on lower frequency,are applied to torpedo passive homing detection.This paper introduces the component parts and the implementing method of the vector sensor,and designs the hardware module and the related system software based on parallel digital signal processors(DSP).The experimental results show that the detection range can be enlarged,and the direction of arrival(DOA) estimation can be more accurate by using the vector sensor.
