基于长基线(TDOA)落点目标定位技术

Research on target location technology based on long baseline(TDOA)

海上试验靶场中武器装备落点的精确测量是考核打击精度的关键问题,为提升武备落点精度测量,开展长基线(TDOA)落点目标定位技术研究,针对落点测量场景对落点目标定位进行定位精度分析和仿真计算。于某深海区开展设计指标验证试验,试验结果表明系统可实时显示落水目标位置,具有较高精度的定位结果,为武器装备落点精度测量提供技术支撑。

In the sea test range,the accurate measurement of the landing point of weapons and equipment is the key issue to assess the strike accuracy.In order to improve the accuracy measurement of the landing point of weapons,this paper studies the long baseline(TDOA)landing point target positioning technology,and analyzes the positioning accuracy and simulates the location of the landing point target based on the landing point measurement scenario.The design index of the actual test verification system in the deep sea area of the South China Sea is analyzed,and the test results prove that the system can display the position of the falling target in real time and has relatively high precision positioning results,which provides technical support for the accuracy measurement of the falling point of weapons and equipment.
