摘要
Abstract
Two conventional positioning methods for an underwater moving target, i.e. ship-borne hydrophone array-acoustic beacon tracking positioning method and ship-towed hydrophone array-acoustic beacon tracking positioning method, are of low tracking positioning accuracy, and of difficulty in implementation and equipment maintenance. So we presented an integrated guidance technology by equipping underwater target with optical fibre gyro and adopting differential global positioning system(DGPS) to measure and record in real time the attitude, velocity and position coordinates of an underwater moving target. The position coordinate data of the target are converted to synchronous underwater acoustic multi-frequency and multi-pulse time-delay encoded signal for transmission, and the encoded signal is measured by ship-towed hydrophones and real-timely resolved by ship-borne base station, thus the measuring and control ship can be guided to accomplish the tasks of tracking, positioning, and monitoring an underwater target at long range in real time. The sea trial result demonstrates the effectiveness of the proposed positioning technology.关键词
