摘要
为了准确获取水下运动目标的运动轨迹,提高测量的数据率,提出了一种基于合作目标的激光水下定位方法。通过在被测目标上加装合作目标,利用合作目标的全反射特性,实现了脉冲式激光水下测角与测距的功能。介绍了激光水下定位的方法和系统组成,给出了水下定位的数学模型及测量结果。模拟实验结果表明,该方法具有一定的工程应用价值。最后,结合工程应用,对激光水下定位需要解决的一些实际问题进行了分析。
A underwater laser localization method using cooperative targets was proposed to acquire trajectories of underwater moving objectives to improve the tracking data precisely. By installing the moving cooperative targets with total reflection characteristics on a measured objective, the angles and distances between the de- tection system and the objective could be measured by a pulse-laser. The localization method and system struc- ture for underwater detection were introduced and a digital model and measured results for the underwater laser localization were also given. Simulated results show that the proposed method is worth applying to engineering. According to engineering application, some practical problems about underwater laser localization to be solved were analyzed.
