摘　　要：根据同步水声脉冲测距定位原理,利用水下多信道GPS声纳浮标阵-雷载3D段定位技术,对上浮水雷进行跟踪定位。利用多频水声脉冲编码技术扩展水声脉冲发射周期,解决了测量周期模糊与测量数据量匮乏的问题。利用水雷状态感知和节能技术设计的雷载3D,段具有工作状态转换和长时间水声信号发射功能。利用球面交汇定位解法建立了系统跟踪定位精度仿真模型,通过仿真预测出系统同步精度、水声信号时延检测精度、GPS定位精度、水听器位置精度和声速测量精度对系统定位精度的影响,为此项技术的可行性和相关系列测控装备的研制提供了依据。According to the ranging and positioning principle of synchronized underwater acoustic pulse,the positioning technology by underwater multi-channel GPS sonar buoy array_mine-borne 3D segment is used to track and position the rising mines.Multi-frequency underwater acoustic pulse encoded technology is used to expand transmitting period for underwater acoustic pulse.The problems are solved that measurement period is fuzzy and measurement data size is not enough.The mine-borne 3D segment designed by perception of mine states and energy-saving technology has functions on conversion of operational states and transmitting underwater acoustic signals for a long time.The simulated model for the system tracking and positioning accuracy is set up with spherical intersection positioning solution.Influences on the system positioning accuracy are predicted for the system synchronized accuracy,time-delay detection accuracy of underwater acoustic signals,GPS positioning accuracy,hydrophone position accuracy and measurement accuracy of sound velocity.The grounds are provided for the technology feasibility and the development of correlated series of measurement and control equipment.
