摘要
针对鱼雷电磁引信存在声自导发射和鱼雷变速时产生的强脉冲干扰问题,文中从自适应噪声对消的基本原理出发,分析了鱼雷电磁引信消除声自导发射和鱼雷变速时产生强脉冲干扰的方法。在增加噪声接收通道获取相关噪声的基础上,采用自适应噪声对消抑制强脉冲干扰。仿真试验表明,该方法可有效抑制声自导发射和鱼雷变速时产生的强脉冲干扰。
In regard to the strong pulse interference in torpedo electromagnetic fuze caused by acoustic homing launch and speed change of torpedo,the principle of adaptive noise cancellation is adopted to propose a method for eliminating this strong pulse interference.The correlated noise is obtained by increasing noise receiving channel,and then the adaptive noise cancellation is used to suppress the strong pulse interference.Simulation result shows that this method can effectively suppress the strong pulse interference generated in acoustic homing launch and speed change processes of torpedo.
