摘要
在舰船抗冲击试验中,爆炸瞬时爆源与靶船相对位置的确定是试验重点,爆距是否满足要求是保证靶船安全及试验效果的重要指标。采用分时长基线球面交汇原理和GPS联测技术对水下目标进行精确定位。爆源处安装接收水听器提高了试验的安全性,水下靶船不用高精度光纤陀螺,而是安装2个水听器和压力传感器,用于测量靶船航向和位置,克服了漂移随时间而增大等弱点。试验应用表明,系统稳定可靠,定位精度满足试验要求。
The relative positions of explosion source and target is key point in a ship shock trial,explosion distance control is an important indicator of trial.For localization of the explosion source and the target ship the time-sharing long baseline（LBL） spherical intersecting positioning principle and the GPS survey technology are utilized to position the underwater target precisely.Receiving hydrophones installed at the charge improved the security of the test.To measure the course and position of the target ship,the target ship didn＇t use high-precision optical fiber gyro（FOG） but two hydrophones and two pressure transducer.This measure overcomes the weakness of increasing shift with time.The application in test concluds that the system is stable and reliable,and positioning precision satisfies the test requirement.
