摘要
现代化战争对信息技术的依赖日益增强,水中目标识别成为各国夺取海洋战争主动权研究的新领域。有效提取目标的本质特征是目标识别的关键。由于1(1/2)维谱保持了高阶谱的性质但其计算量却相对下降,本文结合自适应滤波理论,采用1(1/2)维谱对船舰辐射噪声进行特征提取,由对特征量的分析表明1(1/2)维谱可以有效对船舰类型识别。
The modern war is growing dependent on information technology, so water target recognition becomes the new field of research to seize the marine war initiative in the world. The essential feature of the effective extraction is the key to the recognition of the target. Since the 1(1/2) dimensional spectrum maintains the properties of the higher order spectrum and its calculation amount is relatively decreased. In this paper, with the adaptive filtering theory, the 1(1/2) dimensional spectrum is used to extract the characteristics of ship radiated noise.The analysis of the feature quantity shows that the 1(1/2) dimensional spectrum can effectively identify the ship type.
