摘要
声学定位方式在海底建设、海底资源开发、水下目标定位等领域具有广泛应用前景。本文提出了一种结合EMD重构方法利用水声瞬态信号定位目标的方案。首先结合相关研究选取定位方式,然后建立定位系统,包括信号放大电路、A/D和D/A转换、滤波,进入控制器后采用EMD方式对采集到的水声瞬态信号去噪重构,然后确定目标位置。
Acoustic positioning has wide application prospects in seabed construction, seabed resource development, underwater target positioning and other fields. In this paper, a method of target location using underwater acoustic transient signals is presented, which combines EMD reconstruction. Firstly, the positioning mode is selected according to the relevant research, and then the positioning system is established, including signal amplification circuit, A/D and D/A conversion, filtering. After entering the controller, EMD is used to denoise and reconstruct the collected underwater acoustic transient signal, and then the target location is determined.
