| 中文摘要 | 众所周知，水下超短基线定位系统有着极其广泛的用途。它可应用于舰艇导航、沉雷探测、水下救生、水下管线的铺设等领域。基于这种原因，本文给出了一种实用的基于正交阵结构的超短基线定位系统的工作原理，并详细地介绍了系统实现的关键技术。首先，本文从超短基线定位的基本原理着手，阐述了建立在超短基线定位基本原理之上的正交阵定位工作原理；论述了正交阵定位系统实现的信号处理算法，详细的介绍了LERNER滤波器的设计思想和数字线性相位LERNER带通滤波器实现的方法、数字正交变频的原理、FFT测相技术以及基于DSP的数字信号处理算法和工程实现。其次，本文对超短基线定位系统（正交阵定位）的工作原理进行了计算机仿真，给出了详实的仿真结果，验证了正交阵定位工作原理的正确性和所采取的信号处理算法的可行性，并且通过DSP软件编程将此算法予以工程实现。最后，本文简要的介绍了正交阵超短基线定位系统的硬件设计和软件的流程图，并给出了系统的部分水池调试和湖上试验数据。 |
| 英文摘要 | It is well known that the underwater ultra_short baseline positioning system plays an important role in many fields, such as the navigation of ship, the searching for sinking torpedo, the underwater lifesaving, the underwater pipeline laying and so on. For this reason, a useful positioning theory of ultra_short baseline based on the across array and the key technology of the system implementation are described in the thesis. Firstly, based on the basic positioning theory of ultra_short baseline, the positioning theory of across array is expounded. The arithmetic of signal processing which deals with the positioning system implementation of across array is also included in the thesis. The LERNER Filter with linear phase, the theory of digital orthogonal frequency conversion and the technology of measuring the phase of a signal by FFT are fully detailed. In addition, the arithmetic and project implementation of digital signal processing based on DSP technology are expatiated. Secondly, a simulator is built, which verifies the correctness of the positioning theory of across array and the feasibility of the arithmetic of signal processing, and the arithmetic has been realized by programming in DSP. In the end, the design of hardware and the flow chart of the software, which deal with the ultra. _short baseline positioning system (based on the positioning theory of across array) are briefly introduced, part debugging data in the pool and experimental data on lake is also included in the thesis. |
