本文所提出的自跟踪弹道测量方法与基于水声原理的水下跟踪测量方法不同。它是利用航空与航天飞行器弹道测量原理来获取水下航行器的弹道数据。这种方法不受水下环境影响,且跟踪范围与水下航行器活动范围一致。文中介绍了水下航行器弹道的六自由度测量方法,包括重现弹道数学模型及具体实施方案,提出了减小测量误差,提高测量精度的措施。试验结果表明,自跟踪弹道测量方法的精度与水下跟踪系统的精度比较接近。
The self-tracking ballistic measurement method proposed in this paper is different from the underwater tracking measurement method based on underwater acoustic principle. It is the use of aviation and spacecraft ballistic measurement principle to obtain underwater vehicle trajectory data. This method is not affected by the underwater environment, and the tracking range is consistent with that of the underwater vehicle. This paper introduces a six degree of freedom measurement method for underwater vehicle trajectory, including reproducing the mathematical model of ballistic trajectory and its concrete implementation plan, and puts forward measures to reduce the measurement error and improve the measurement accuracy. The experimental results show that the accuracy of self-tracking ballistic measurement method is close to that of underwater tracking system.
