一种水声近炸引信,适用于对鱼雷等水下目标实施拦截杀伤的火箭式深弹系统,设计中解决的技术问题有:对水下目标的识别技术、有效的测距方法及抗冲击过载技术。所采用的方法是通过对水下目标辐射噪声信号的能量检测、识别和能量变化的比较以及目标所发出的不同线谱的频率来判断和识别目标。验证试验表明,能对不同目标进行识别,并适时发出起爆信号。

An underwater acoustic-proximity fuze was introduced. It is compatible with the munitions system designed for interrupting and destroying underwater target such as torpedo. During design, there were some technology problems, for example, target identification technology, valid method of measuring sound travel distance and the technology of overload-proof. To distinguish and identify target, several methods were adopted, including testing and identifying sound signal energy variety by the underwater target, comparing with energy change, in addition, through frequency of different line spectrum emitted by different target, etc. The simulation test results show that this fuze can identify different target and give out initiation signal.
