基于正交相关处理的反鱼雷鱼雷声引信接收机的设计

Receiver of Anti-torpedo Ultrasonic Fuze Based on Orthogonal Related Processing

反鱼雷鱼雷攻击来袭鱼雷时,自导装置将其引到来袭鱼雷附近,当声引信装置判定来袭鱼雷在其作用半径之内时,引爆装药,摧毁来袭鱼雷。文中对主动非触发引信接收样本信号进行分析,分析结果表明反鱼雷鱼雷的接收机可采用正交接收机,并阐述其理论模型、工作原理、电路组成及导出正交处理电路的理论处理增益,最后实验结果表明处理增益可以满足技术要求。

When anti-torpedo torpedo attacks incoming torpedo, its homing device lead it near the incoming torpedo, when acoustic fuze device judges that the incoming torpedo is within the radius of action, it sets off the detonator to destroy the incoming torpedo. Aiming at the analysis of the interference of active noncontact fuze, this paper holds that the receiver of anti-torpedo can adopt orthogonal receiver. Theoretical model, principle, composing of the circuit and the theoretical pro- cessing gain of orthogonal processing circuit are also expatiated, lastly the experimental result shows that processing gain can meet the technical requirements.
