摘要
针对深海采矿水下三维定位的需要,利用调幅超声波基阵原理,研究了一种对水下运动物体三维定位系统,建立了模拟实验装置并进行了前期实验。实验结果表明三维定位误差接近厘米级精度,验证了该系统的可行性,为工程实现提供了技术原型。
For deep-sea mining underwater three-dimension positioning, a 3-D ultrasonic position system of athletic object under- water was introduced by means of the principle array of amplitude modulated ultrasonic, and the simulation devices were established. The feasibility of this method in principle was validated through the simulating test and the positioning error is close to centimeter-level accuracy. The system provides technical prototype for implementation of the project.
