| 中文摘要: |
| 提出了利用垂直接收阵和不同距离上的两枚宽带引导声源重构声场对目标声源进行定位的一种方法。这种方法主要基于简正波提取和声场重构两种关键技术,避开了传统的匹配场目标定位技术对环境先验知识的依赖性,同时省去了大量的拷贝声场计算。介绍了在浅海均匀环境中,利用宽带引导声源重构拷贝声场的目标声源定位技术。主要采用线性Bartlett匹配处理器分析了目标定位效果,在信噪比高于10dB的情况下,定位效果良好。 |
| 英文摘要: |
| A new method of object source ranging by use of vertical receiver array and the broadband guide source to reconstruct acoustic fields is presented. This method, mainly based on normal modes extraction and acoustic field reconstruction technique, can greatly reduce the requirement of environment parameters and avoid the complicated computation of replica field for matched field processing localization. Object source localization in range-independent shallow water environment using broadband guide sources to reconstruct the replica field is presented. Linear Bartlett processor is used to give the object locating results. Good results is obtained when the Signal-Noise ratio is higher than 10dB . |
