【摘要】：为了解决座底式长基线水声跟踪系统的高效校阵问题,结合工程项目实际提出一种智能化分组并行校阵方法。该方法利用水下基阵布阵施工时获得的水声及差分全球定位系统(Differential Global Positioning System,DGPS)测量数据为基准,在校阵试验中采用多个水下基阵分组并行校阵的快捷方式,根据自动反馈的测量数据进行校阵误差收敛测量,当满足事先设定的校准误差后,获得水下基阵的精确位置信息,同时完成多个水下基阵的阵型校准。最后,在某水域采用跑船试验的方式进行验证。长基线系统测量的船只航行轨迹与DGPS轨迹重合性好,证明该方法具有智能化程度高、测量精度高、测阵效率及经济性好等优点,具有较高的军事及民用价值。
[Abstract]:In order to solve the problem of high efficiency alignment of underwater acoustic tracking system with long base line, an intelligent grouping and parallel array calibration method is proposed according to the actual engineering project. Based on the underwater acoustic and differential Global Positioning system (DGPS) data obtained during the underwater array construction, the method adopts a quick method of multiple underwater array grouping and parallel alignment in the experiment of underwater array, which is based on the data of underwater acoustic array and differential Global Positioning system (DGPS). According to the measured data of automatic feedback, the calibration error convergence measurement is carried out. After the pre-set calibration error is satisfied, the accurate position information of the underwater array is obtained, and the calibration of several underwater arrays is also completed at the same time. At last, the method of running ship test is used to verify it in a certain water area. It is proved that this method has the advantages of high intelligence, high measuring precision, good efficiency and economy of measuring array, and has high military and civil value.
