摘　　要：研究了一种基于相关分析方法的超声波水下定位系统,讨论了其主要原理及其设计方法,并进行了前期试验,通过在空气中的模拟检测验证了该方法在原理上的可行性,同时精度能达到设计时的要求,取得了预期的效果。该方法经改进后,可应用于深海采矿升沉补偿系统中,为采矿船提供实时、准确的升沉位移数值。An ultrasonic positioning system based on correlation analysis and used underwater was introduced, the principle and design were discussed. The feasibility of this method in principle was validated through the simulating test in the air and the precision could fulfill the request of the system. The expected effect in this test was gotten. After being improved, this system can be uesd in the heave compensation system for deep sea mining system, and provides real time and exact heave distance for the mining ship.
