利用目标噪声频域信息的定位方法研究

The Research on Localization Method using the Information of Frequency Domain of a Target Radiated Noise

讨论了水雷声引信对目标被动定位的重要性，提出了基于互谱法测向的基本原理，着重研究了利用舰船辐射噪声的线谱分量进行加权平均获取时延并提高测向精度的技术。仿真实验证明了本文方法的正确性和有效性。

In this paper, the importance of passive localization of the acoustic fuze for a mine to target is discussed, and an algorithm of using cross spectrum analysis is proposed. This papaer puts emphasis on the study of weighting average of line components of ship radiated noise spectrum to get improved bearing estimation precision to the target. The simulation algorithm has been used to confirm the reliability of the principle.
