| 摘 要： | 针对在实际海洋中对舰船轴频电场进行远程探测的问题,文中采用了一种基于高阶FS谱对角切片的微弱信号处理技术,通过该方法能简单有效地将微弱轴频电场信号从低信噪比的实测数据中分离出来.最后使用该方法和基于高阶谱对角切片的弱信号检测方法,分别对同一组实测的舰船轴频信号进行了处理,结果对比表明该方法的有效性. |

| Abstract: | The remote testing of the Shaft-Rate Electric Field of the Ship in the real ocean is a difficult task,this paper put forward a weak signal processing method based on the diagonal slice of FS polyspectra,and by using this method the characteristic signal can be extracted effectively from the experiment data of low SNR.In the end of this paper,this method and the method based on the diagonal slice of the HOS are both used to process the same experiment data,the validity of this method is proved by contrasting... |
