摘要
在鱼雷试验中,为了能及时有效地掌握鱼雷水下工作情况,需要第三方监测设备对鱼雷和目标靶信号进行实时记录和分析,为事后恢复现场查找问题提供有力的数据支持。本文通过分析鱼雷试验现场的基本情况,提出了一种基于快速傅里叶变换(FFT)技术的时域和频域相结合的雷靶信号识别方法。鱼雷试验中使用该雷靶监测设备时的信号监测效果,验证了该方法的有效性。
In order to efficiently understand torpedo working condition under water in torpedo trials, a third-party monitoring system is usually used to simultaneously record both signals of torpedo and target for subsequent analysis. In this study, sea trial scenario is analyzed, and a fast Fourier transform-based both signals identification method is pro- posed by combining time domain with frequency domain for torpedo-target monitoring system. Identification results of the monitoring system in a sea trial verify the validity of the proposed method.
