本文根据短基线水声跟踪系统的实际使用情况,得出一种较为简单的的近似计算方法,可用来实时处理水声跟踪系统的测量数据。理论计算结果表明,应用本文中提出的计算方法,在1270米跟踪范围内,有可能把深度坐标的计算误差约束在3米以内,把水平射程的计算误差约束在2米以内。这样的计算精度,对于实时处理水中运行体的跟踪问题完全够用了。在附录中给出了短基线水声跟踪系统的定位原理。
Based on the actual use of short baseline acoustic tracking system, this paper presents a simple approximate calculation method, which can be used to process the measurement data of underwater acoustic tracking system in real time. The theoretical calculation results show that it is possible to restrict the calculation error of depth coordinates to within 3 meters and the calculation error of horizontal range to within 2 meters within the tracking range of 1270 meters by using the calculation method proposed in this paper. This calculation accuracy, for real-time processing of water running body tracking problem completely enough. The positioning principle of the short baseline acoustic tracking system is given in the appendix.
